Bosshead

Bossheads 18/10 Stainless Steel (Product Code: SLE/BH/01) is a 90° stainless steel bosshead used to fix clamps, rings and cross rods to the upright rod of a retort stand in school, college and research laboratories. It is listed in thread 6 and thread 8 versions, both with a d/Ø figure of 16,5, and takes a socket screw, heart screw or heart-type safety screw. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of lab stand hardware, at its own factory in Ambala, India.

Specifications

What Is the Stainless Steel Bosshead Used For?

A bosshead is the joint that turns a plain stand rod into a working support. One bore slides onto the vertical rod of a retort stand and is tightened in place; a clamp shank or horizontal rod goes into the second bore at 90° and is locked with the other screw. In practice this holds burette clamps for titration, condenser and flask clamps for distillation, and rings for funnels or wire gauze. The 18/10 grade (18% chromium, 10% nickel) resists rust and staining on benches where acids, salt solutions and water are handled every day.

Choose the screw style to suit the users. A socket screw needs a hex key and suits setups that should not be adjusted casually, a heart screw is tightened by hand for quick changes, and a safety screw is designed to stay with the bosshead so it is not lost. Tighten both screws firmly before loading glassware, keep the load over the stand base and wipe the bosshead dry after spills.

What to Specify When Ordering

• Thread version: 6 or 8 (both are 18/10 stainless steel with d/Ø 16,5 and a 90° angle).
• Screw type: socket screw, heart screw or heart-type safety screw.
• The diameter of your stand rods, so we can confirm the fit of the d/Ø 16,5 figure (the listing gives no unit).
• Quantity per laboratory or per bench, including a few spares for rearranging apparatus.

Bosshead Malleable Cast Iron Chromium Plated (Product Code: SLE/BH/02) is a chrome-plated 90° bosshead used to join clamps, rings and cross rods to stand rods where a setup carries heavier apparatus or thicker rods. Cast in malleable (tempered) cast iron, it is listed in three sizes, d/Ø 16,5, 20,0 and 36,0, all with thread 8, and takes a heart-type safety screw or a thumb screw. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Ambala, India.

Specifications

What Is the Chrome-Plated Cast Iron Bosshead Used For?

Malleable iron is cast iron that has been heat-treated to make it tougher and less brittle, so a bosshead made from it tolerates repeated tightening and the occasional knock without cracking. The chromium plating protects the iron and gives a bright surface that is easy to wipe. On the bench, the bosshead holds clamps, rings and cross rods at right angles to an upright rod: supporting a separating funnel, fixing a condenser during distillation, or joining rods into a frame for a physics demonstration.

The three d/Ø sizes let you match the bosshead to the rods you already use, with the larger versions intended for thicker rods and heavier frameworks such as those in lab equipment for technical institutes. Fit the thumb screw where users adjust heights often, or the safety screw where the screw should stay with the bosshead. Tighten firmly, test the joint by hand before hanging glassware, and dry the plating after it is splashed.

What to Specify When Ordering

• Size: d/Ø 16,5, 20,0 or 36,0 (all thread 8, 90° angle).
• Screw type: heart-type safety screw or thumb screw.
• The diameter of the rods you use, so we can match the right size (the listing states no unit).
• Quantity for each size, if your laboratory runs rods of different thicknesses.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM for this chrome-plated bosshead and makes it at the company's own licensed factory at Saha, Ambala, Haryana, India. It is supplied straight from there to school and college laboratories, technical institutes, distributors and importers in India and international markets, without a trading middleman.

Because all three sizes come from the same maker, a mixed order is quoted and packed together, and repeat supplies or spare screws can be requested from the manufacturer directly. Details about the company are on the profile page.

Bosshead Aluminium (Product Code: SLE/BH/03) is a lightweight aluminium connector used to join a clamp, ring or cross rod to a stand rod at 90° in school and college laboratories. Teachers and lab assistants pick it for student stands because it is easy to carry, and it is listed with d/Ø 16,5, thread 8 and a choice of socket, thumb or heart-type safety screw. Jain Scientific Equipments Pvt Ltd (ScienceLab) makes it as an OEM manufacturer at its own factory in Ambala, India.

Specifications

What Is the Aluminium Bosshead Used For?

Aluminium is much lighter than steel or cast iron, so a tray of these bossheads is easy for students to carry to their benches and a finished stand is less likely to tip. That makes the aluminium bosshead a sensible pick for junior and secondary practicals: holding a thermometer clamp over a beaker, fixing a pendulum support rod, clamping a test tube for heating or attaching a ring for a filter funnel. Aluminium does not rust in ordinary lab conditions, so the fitting stays presentable with little care.

Match the screw style to the class: thumb screws let students change heights quickly, socket screws need a hex key and keep fixed setups from being altered, and the heart-type safety screw is intended to stay with the bosshead instead of going missing. Keep aluminium away from strong alkalis such as sodium hydroxide, which attack the metal, and rinse off any splash straight away. A light bosshead like this is standard physics lab equipment for school practical classes where assemblies are built and taken down within one period.

What to Specify When Ordering

• Screw type: socket screw, thumb screw or heart-type safety screw.
• Your stand-rod diameter, so that the d/Ø 16,5 and thread 8 listing can be confirmed as a fit.
• Quantity per lab or per student station, including spares.
• Any stands, rods or clamps you want quoted together with the bossheads.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, and the company is the OEM (original equipment manufacturer) of this aluminium bosshead, making it at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, laboratory dealers and importers buy it factory-direct, so screw options and repeat orders are discussed with the maker itself rather than a trader.

The Bosshead Aluminium is lighter than steel or cast iron versions and does not rust in normal lab use, which suits student stands, portable demonstration kits and classes where assemblies are built and dismantled every period.

What are the key dimensions of the Bosshead Aluminium?
The Bosshead Aluminium is catalogued with d/Ø 16,5 (sixteen and a half, written with a decimal comma), thread 8 and a 90° angle. Units for d/Ø are not stated in the listing, so share your rod diameter and ScienceLab will confirm the fit.

Which screw types are available for the Bosshead Aluminium?
The Bosshead Aluminium is listed with three screw options: a socket screw tightened with a hex key, a thumb screw for quick adjustment by hand, and a heart-type safety screw. Name your preferred screw in the enquiry so the quotation matches.

Is the Bosshead Aluminium affected by laboratory chemicals?
Strong alkalis such as sodium hydroxide attack aluminium and some acids can mark it, so rinse and dry the Bosshead Aluminium after any splash. For benches with constant corrosive work, a stainless steel bosshead from the same range is the better option.

Who manufactures the Bosshead Aluminium?
The Bosshead Aluminium is an OEM product of Jain Scientific Equipments Pvt Ltd (ScienceLab), made at the company’s own factory at Saha, Ambala, Haryana, India. Schools, dealers and importers receive it factory-direct, with quotations issued by the manufacturer.

How do I keep the screws of the Bosshead Aluminium working smoothly?
Avoid over-tightening the Bosshead Aluminium, wipe its thread clean from time to time and store the bossheads dry in a tray rather than loose in a drawer, where screws can be knocked, bent or lost.

Can ScienceLab supply the Bosshead Aluminium for a whole class or for export?

Bosshead Cross Type 18/10 Stainless Steel (Product Code: SLE/BH/04) is a cross-pattern stainless steel bosshead used to clamp two rods either at right angles or in line (angle 90+180) when building frames and extended supports in laboratories. It is listed with d/Ø 16,5 in thread 6 and thread 8 versions, takes socket, heart or heart-type safety screws, and suits wet chemistry rooms where corrosion resistance matters. The bosshead is produced by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer working from its own factory in Ambala, India.

Specifications

What Is the Cross Type Stainless Steel Bosshead Used For?

The extra 180° position is what sets this bosshead apart. At 90° it behaves like a normal bosshead, holding a clamp or cross-bar out from the stand rod; at 180° the two rods run side by side, which is useful for extending a rod, doubling up a support so a long condenser is held at two points, or building a rectangular frame over a bench for a chromatography tank or gas collection setup. Because both positions come from one fitting, technicians can keep fewer parts in stock while still covering most arrangements.

The 18/10 stainless steel body resists acids, salt solutions and cleaning agents, so it suits wet chemistry and biology rooms as well as laboratory distillation apparatus in college practicals. Tighten one screw at a time, check the alignment of the second rod before the final turn, and never hang glassware from a joint that has not been checked by hand.

What to Specify When Ordering

• Thread version: thread 6 or thread 8 (both listed with d/Ø 16,5).
• Screw type: socket screw, heart screw or heart-type safety screw.
• Your rod diameter, so the fit can be confirmed before quotation.
• Number of cross bossheads per frame or per lab.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM behind this cross-type bosshead. It is produced at the company’s own licensed factory in the HSIIDC Industrial Area at Saha, Ambala, Haryana, India, and sold factory-direct to schools, universities, research laboratories, dealers and importers. When you later need matching bossheads or replacement screws, ask the manufacturer directly. The company profile has more background.

Bosshead Cross Type Malleable Cast Iron Chromium Plated (Product Code: SLE/BH/05) is a chromium-plated, tempered cast iron cross connector used to lock two rods at 90° or 180° to each other when building rigid support frames in physics, engineering and chemistry labs. It is listed with d/Ø 16,5 and thread 8 and is fitted with either a heart-type safety screw or a thumb screw. It comes from Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM manufacturer that makes it at its own factory in Ambala, India.

Specifications

What Is the Chromium-Plated Cross Bosshead Used For?

When a setup needs more than one upright, a cross-type bosshead links the rods into a frame. In a mechanics lab, two stands joined by a horizontal bar through cross bossheads can carry pulleys, a spring balance or a pendulum without wobbling, and in chemistry the same arrangement holds a long reflux or distillation train at several points. The heat-treated malleable iron body is tough enough for regular tightening and loosening, and the chromium plating keeps the surface clean and resistant to rust.

Choose the thumb screw for frames that are rearranged often and the safety screw where the screw should stay with the bosshead. As part of mechanics lab equipment in India’s school and college laboratories, tighten each joint firmly, confirm the frame is square before adding weights, and dry the plated surface after any spill.

What to Specify When Ordering

• Screw type: heart-type safety screw or thumb screw.
• Your rod diameter, to confirm the d/Ø 16,5 and thread 8 listing suits your stands.
• How many cross joints each frame needs, plus spares.
• Matching plated bossheads, bases or clamps to be quoted in the same enquiry.

OEM Manufacturer

The company behind the ScienceLab name, Jain Scientific Equipments Private Limited, is the OEM of this cross bosshead and makes it at its own licensed factory at Saha, Ambala, Haryana, India. It is a registered MSME manufacturer (Udyam UDYAM-HR-01-0003714) and ships export orders under Importer-Exporter Code AAECJ8618A issued by the DGFT.

Frequently Asked Questions

How does the Bosshead Cross Type Malleable Cast Iron Chromium Plated differ from a standard bosshead?
Its angle is listed as 90+180, so the Bosshead Cross Type Malleable Cast Iron Chromium Plated can clamp rods crossing at 90° or aligned at 180°. A standard bosshead holds only the 90° position, which limits it to simple clamp arrangements.

What rod size and thread does the Bosshead Cross Type Malleable Cast Iron Chromium Plated have?
The Bosshead Cross Type Malleable Cast Iron Chromium Plated is catalogued with d/Ø 16,5 (decimal comma) and thread 8. The unit is not given in the listing, so share your rod diameter with ScienceLab for confirmation before ordering.

Bosshead (Product Code: SLE/BH/06) is a general-purpose laboratory bosshead used to connect clamps, rings and cross rods to stand rods at 180° or 90° in chemistry, physics and biology rooms. It is listed in three versions — 18/10 stainless steel (d/Ø 16,5, thread 8), aluminium (d/Ø 16,5, thread 8) and a larger aluminium version (d/Ø 27, thread 10) — with four screw styles. All three versions are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Laboratory Bosshead Used For?

This listing is useful when one order has to cover different stands in a building. The stainless version handles corrosive wet-chemistry benches, the standard aluminium version keeps student stands light, and the larger aluminium version with d/Ø 27 and thread 10 is intended for thicker rods. Because every version offers both 180° and 90° positions, the same bosshead can hold a clamp out from the rod or line up a second rod alongside it.

In daily use, slide the bosshead onto the stand rod, tighten it at working height, insert the clamp shank or cross rod in the second bore and tighten again. Safety screws suit shared teaching labs because they are meant to stay attached, while plain heart or thumb screws are quicker to swap. For a complete school laboratory setup in India, order spare bossheads for each retort stand so complex setups can be built without dismantling others.

What to Specify When Ordering

• Version: 18/10 stainless steel (d/Ø 16,5, thread 8), aluminium (d/Ø 16,5, thread 8) or aluminium (d/Ø 27, thread 10).
• Screw style: heart screw, thumb screw, or safety screw of heart or thumb type.
• Your rod diameter, so the matching d/Ø size is chosen.
• Quantity of each version if you are equipping several rooms.

OEM Manufacturer

This bosshead is an OEM product of Jain Scientific Equipments Private Limited, the company that trades as ScienceLab. All three listed versions are manufactured at its own licensed factory at Saha, Ambala, Haryana, India, so a school or dealer can order a mix of stainless and aluminium versions from one maker in one quotation.

Bosshead Swivel Type, 18/10 Stainless Steel (Product Code: SLE/BH/07) is a swivelling stainless steel bosshead used to hold a clamp or rod at any angle from 0 to 360° on a laboratory stand. Chemistry and physics teachers use it to set condensers, delivery tubes and optical parts on a slope; it is listed with d/Ø 16,5, thread 6 and a heart screw for tightening by hand. Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures it as the OEM at its own factory in Ambala, India.

Specifications

What Is the Stainless Steel Swivel Bosshead Used For?

Many classic setups need something held at a slant: the sloping condenser of simple laboratory distillation apparatus, a boiling tube angled over a flame, a delivery tube running into a gas jar, or a mirror or lens tilted for an optics experiment. A fixed right-angle bosshead forces the clamp to be twisted or wedged, which is neither safe nor repeatable. With a swivel bosshead the angle is set by rotating the joint and then locking it, so the apparatus sits steadily and the next group can reproduce the same geometry.

Fix the bosshead to the stand rod, fit the clamp or rod in the second bore, swing it to the required angle and tighten the heart screw firmly. Support the weight of glassware while you adjust, and recheck the angle after tightening. The 18/10 stainless steel construction stands up to acids, salt solutions and routine washing in chemistry and biology rooms.

OEM Manufacturer

Jain Scientific Equipments Private Limited (trading as ScienceLab) is the original equipment manufacturer (OEM) of this swivel bosshead, which is produced at the company’s own licensed factory at Saha, Ambala, Haryana, India. Because the maker sells direct to schools, colleges, research labs, dealers and importers, questions about matching clamps or a replacement heart screw can be put to the factory itself.

Bosshead Swivel Type, Malleable Cast Iron, Chromium Plated (Product Code: SLE/BH/08) is a rotating bosshead used to join a clamp shank or cross rod to a stand rod and lock it at any angle through 0-360° in school and college laboratories. Its tempered cast iron body is chromium plated and tightened by a thumb screw, and it is listed with d/Ø 16,5 and thread 8. It is an OEM product of Jain Scientific Equipments Pvt Ltd (ScienceLab), made at the company’s own factory in Ambala, India.

Specifications

What Is the Chromium-Plated Swivel Bosshead Used For?

Plenty of practicals need something held on a slope: a test tube tilted over a burner so condensate cannot run back onto hot glass, a delivery tube angled into a gas jar, a thermometer set into a side-arm flask, or an inclined track or mirror in a physics demonstration. In distillation apparatus on a school bench, the swivel joint lets the condenser fall gently towards the receiver without forcing the clamp. It is a useful part of any retort stand lab setup where apparatus must lean rather than sit square to the stand.

Tighten the stand-rod side first, pass the clamp shank through the other side, rotate it to the angle you need and lock it with the thumb screw, keeping a hand under any glassware while you adjust. The chromium plating gives a bright surface that is easy to wipe; rinse off acid or salt splashes promptly and dry the joint so the plating stays intact.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM that makes this chromium-plated swivel bosshead at its own licensed factory at Saha, Ambala, Haryana, India.

What Is the Stainless Steel Frame Bosshead Used For?

A frame takes over when one retort stand is not enough: a distillation train where flask, condenser and receiver each need their own support, a reflux setup that runs long heating steps, a rack of chromatography columns, or a demonstration rig with several hanging points. Bossheads for frames lock onto the frame tubes and carry horizontal or vertical rods at a true right angle, turning the frame into a grid on which clamps can be placed exactly where the glassware sits.

Plan the positions before tightening anything, then fix the frame side first and the rod side second. A ring screw is handy where positions are changed often by hand, while a socket screw suits setups that should stay fixed once assembled. As one of the core lab equipment accessories for wet chemistry rooms, the 18/10 stainless body copes well with acid fumes, spills and repeated washing.

What to Specify When Ordering

• Which screw you want fitted: a ring screw or a socket screw.
• Frame tube and rod sizes, to confirm the d/Ø 13,5 and thread 6 listing.

Specifications

What Is the Chromium-Plated Frame Bosshead Used For?

Mechanics experiments often need a rigid overhead bar: a pulley system for a lesson on mechanical advantage, a simple pendulum hung clear of the bench, a spring and slotted-mass arrangement for Hooke’s law, or a pair of rods carrying an optics accessory. Fitted to an H-frame or a base-plate stand, this bosshead holds each cross rod square to the upright so loads hang vertically and readings stay consistent between groups. That makes it everyday physics lab equipment for schools in India that run demonstration frames.

Slide the bosshead to height on the frame tube, tighten it, then insert the cross rod and lock it. Use the ring screw where students adjust heights by hand; the socket screw keeps a teacher-built rig from being loosened casually. The plated surface stays bright on dry physics benches with a simple wipe.

What to Specify When Ordering

• Screw type: ring screw or socket screw.
• Frame tube and rod diameters, checked against the d/Ø 13 and thread 6 listing.

Hook Bosshead, 18/10 Stainless Steel (Product Code: SLE/BH/11) is a hook-type stainless steel bosshead used to join a clamp or cross rod to a stand rod at 90° on titration, filtration and heating setups. It is listed with d/Ø 13, thread 8 and a heart screw for firm hand tightening, and its 18/10 stainless body suits wet chemistry benches. This bosshead is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as an OEM at its own factory in Ambala, India.

Specifications

What Is the Hook Bosshead Used For?

On a crowded stand, a hook-style boss head is generally chosen so that a fitting can be added or taken off part-way up the rod without dismantling the clamps above it. Typical jobs include fixing a burette clamp for titration, adding a ring for a filter funnel, or setting a side rod for a thermometer over a water bath. Because it holds the second rod at a firm 90°, the clamp stays level and glassware hangs straight, which matters when students read a burette or meniscus.

Position it on the stand rod, seat the clamp shank or cross rod in the hook side and turn the heart screw until the joint is rigid; take the weight of any glassware off the clamp before loosening. In busy school chemistry lab equipment rooms, 18/10 stainless steel is a sensible choice because acid splashes and daily washing do not mark it the way they can mark coated metals.

OEM Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited, which is the OEM of this hook bosshead and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Buying from the manufacturer means schools, colleges, dealers and importers get quotations without a middleman and can ask the factory directly about matching fittings.

Three Angle Bosshead (Product Code: SLE/BH/12) is a duraluminium rod connector used to join support rods at 90°, 180° and 270° positions in multilevel and three-dimensional laboratory constructions. Engineering, physics and research labs choose this lab stand clamp boss head when a frame must branch in three directions from one node, and it is catalogued in two versions, for d/Ø 9-13 and d/Ø 19-23. ScienceLab is the OEM: Jain Scientific Equipments Pvt Ltd (ScienceLab) makes it at its own factory in Ambala, India.

Specifications

What Is the Three Angle Bosshead Used For?

Ordinary bossheads join two rods in one plane. When a rig has to grow in three dimensions — a cube-like frame around a reaction vessel, a multilevel support carrying a flask on one tier and a condenser on the next, or a demonstration structure for engineering students — a connector that accepts rods at 90°, 180° and 270° saves stacking several bossheads at the same point. Fewer joints mean a stiffer frame and less slipping under load.

Pick the version that matches your rods: d/Ø 9-13 for lighter frameworks and d/Ø 19-23 for heavier, larger structures. Build from the base upward, tighten each joint before adding the next level, and check the frame for squareness once it carries weight. Duraluminium, an aluminium alloy valued for strength at low weight, keeps even a complete lab setup of rod frameworks manageable to move and re-arrange.

What to Specify When Ordering

• The version: d/Ø 9-13 or d/Ø 19-23, matched to the rods in your frame (the listing gives no unit, so send your rod diameter).
• How many connectors each frame needs and how many frames you are building.
• Any rods, bases or other bossheads to be quoted together for the complete structure.

OEM Manufacturer

ScienceLab is the OEM (original equipment manufacturer) of the Three Angle Bosshead. Jain Scientific Equipments Private Limited, which trades as ScienceLab, produces it at its own licensed factory at Saha, Ambala, Haryana, India, rather than sourcing it from a trader. Research labs, institutions, dealers and importers buy it factory-direct, and repeat orders or replacement screws are handled by the manufacturer itself — just ask us.

Frequently Asked Questions

What does "three angle" mean on the Three Angle Bosshead?
The Three Angle Bosshead provides clamping positions at 90°, 180° and 270°, so rods can branch in three directions from a single joint. One duraluminium connector can therefore replace several stacked bossheads at the corners and crossings of a multilevel or three-dimensional rod frame.

Which version of the Three Angle Bosshead should I order?
Order the Three Angle Bosshead version that matches your rods: one is catalogued for d/Ø 9-13 and the other for d/Ø 19-23, both with thread 4. The listing does not state the unit, so send your rod diameter through the contact page and ScienceLab will confirm the correct version.

Is the Three Angle Bosshead strong enough for loaded frames?
The Three Angle Bosshead is described as suitable for multilevel and three-dimensional constructions because of its strength, and duraluminium keeps large frames light to move. For unusually heavy apparatus, share the load and frame layout with ScienceLab before ordering so the right version can be advised.

Who manufactures the Three Angle Bosshead?
The Three Angle Bosshead is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Buyers deal directly with the manufacturer for quotations, repeat orders and replacement screws instead of going through a trader.

How should a Three Angle Bosshead be maintained?
Keep the Three Angle Bosshead clean and free of grit around its screws, and avoid over-tightening, which can mark softer aluminium alloys. When a duraluminium frame is dismantled, store the connectors together with their screws so each three-direction joint can be rebuilt quickly for the next setup.

What should a quotation request for the Three Angle Bosshead include?
A quotation request for the Three Angle Bosshead should give the code SLE/BH/12, the version (d/Ø 9-13 or 19-23), the quantity and the delivery location. ScienceLab quotes directly as the manufacturer for institutions, dealers and importers in India and international markets.

Squared Bosshead (Product Code: SLE/BH/13) is an 18/10 stainless steel connector used to clamp two rods square to each other in rod frameworks and fixed laboratory rigs. It is catalogued at d/Ø 12-13 x 12-13 with a 90° angle, tightened with hexagon socket screws, and can be combined with a connection bar (d = 12 mm x 50 mm) to adjust the angle from 0-360°. Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, produces it at its own factory in Ambala, India.

Specifications

What Is the Squared Bosshead Used For?

A squared bosshead is the connector of choice when a rod framework must stay exactly square: a grid of rods above a bench holding sensors or electrodes, a fixed support for a column or condenser that should not drift between sessions, or a test rig in an instrument or process lab. Hexagon socket screws sit neatly and are tightened with a hex key, so the joint is not loosened casually by students passing the bench. That makes it a tidy, tamper-resistant version of the familiar lab stand clamp boss head for shared rooms.

For angled work, add the connection bar: it lets the joint be set anywhere in the 0-360° range while keeping stainless parts throughout. Keep a correctly sized hex key with the rig, tighten screws evenly, and clean off chemical residues so the stainless steel keeps its finish.

What to Specify When Ordering

• Which listing you need: d/Ø 12-13 x 12-13 at 90°, or the d/Ø 12 entry.
• Whether the connection bar (d = 12 mm x 50 mm) is required for angle adjustment.
• Rod diameters in your framework.
• Quantity of bossheads per rig.

OEM Manufacturer

Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597) trades as ScienceLab and is the OEM of this squared bosshead, manufacturing it at its own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, India (Factory Licence AMB-ONLINE-CHD-J-414). Laboratories, institutes, dealers and importers buy it factory-direct, and questions about the connection bar or repeat orders go straight to the maker. See the company profile for more.

Frequently Asked Questions

What rods does the Squared Bosshead take?
The Squared Bosshead is catalogued at d/Ø 12-13 x 12-13, meaning both clamping sides are listed for the 12-13 range. If your rod sits at the edge of that range, confirm the size with ScienceLab via the contact page.

Can the Squared Bosshead hold rods at angles other than 90°?
On its own the Squared Bosshead holds rods at 90°. Combined with a connection bar (d = 12 mm x 50 mm), the angle can be adjusted from 0-360° while the framework stays in stainless steel.

Is the connection bar included with the Squared Bosshead?
The connection bar is presented as a combination option for the Squared Bosshead rather than a standard part. Tell ScienceLab if you need it, and your quotation will list exactly which items are supplied.

What tool is needed to tighten the Squared Bosshead?
The Squared Bosshead uses hexagon socket screws, so it is tightened with a hex (Allen) key. This keeps the joint neat and makes it harder for a fixed rig to be loosened by accident.

What is the second Squared Bosshead listing with d/Ø 12?
The catalogue shows a second 18/10 stainless steel Squared Bosshead entry at d/Ø 12 with no fixed angle stated. Ask ScienceLab which entry suits your setup, and the difference will be explained in the quotation.

Safety Screw 18/10 Stainless Steel (Product Code: SLE/BH/14) is a stainless steel clamping screw with a swivelling steel head, used to secure bossheads and other stand connections in school and college laboratories. Technicians keep it as a spare so a lost or worn screw does not put a retort stand out of use; it is catalogued with length 65, width 32 and D/Ø 8. The screw is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of stand hardware, at its own factory in Ambala, India.

Specifications

Dimensions are shown as catalogued; the unit is not stated in the listing.

What Is the Stainless Steel Safety Screw Used For?

Every bosshead and clamp depends on its screw. In a teaching lab, screws are the part most often lost, bent or cross-threaded, and a stand with a missing screw usually ends up in a drawer. Keeping stainless safety screws among your lab equipment spare parts lets a technician restore a stand in minutes, and the swivelling steel head is the feature that distinguishes this screw from a plain one.

Before fitting, clean the threaded hole of the bosshead, start the screw by hand to avoid cross-threading, and tighten until the rod is held firmly without forcing it. Collect screws from stands at the end of term and check them for damaged threads. The stainless body resists the acid fumes and wet benches that corrode ordinary steel hardware.

Bosshead, Coated Aluminium, Black (Product Code: SLE/BH/15) is a die-cast, double-head bosshead used to hold rods of 5-20mm on retort stands in school and college laboratories. The wide rod range lets one fitting grip both slim clamp shanks and thicker stand rods, and metal clamping screws tighten each head securely. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Black Coated Aluminium Bosshead Used For?

The double head is the working principle of any bosshead: one head grips the upright stand rod, the other grips the clamp or cross rod. The wide 5-20mm range is the practical advantage here, because one design accepts the thin rods of burette, test-tube and thermometer clamps as well as heavier support rods, so a lab does not need separate bossheads for every clamp. It is a sensible line for school lab equipment bulk supply, when dozens of stands are fitted out for practicals in heating, titration and filtration.

Tighten the stand-rod head first, then position and lock the clamp, and check both screws before loading glassware. The black coating protects the aluminium and gives a uniform look across a lab; avoid scraping it with tools and wipe off spills promptly.

OEM Manufacturer

Jain Scientific Equipments Private Limited — ScienceLab to its customers — is the OEM of this black coated bosshead, producing it at its own licensed factory at Saha, Ambala, Haryana, India. Schools fitting out many benches, as well as dealers and importers, can therefore order class quantities straight from the manufacturer and ask it about matching stands and clamps. More is on the company profile.

Bosshead, Metal (Product Code: SLE/BH/16) is a die-cast alloy bosshead used to hold two retort stand rods at right angles to each other in school titration, heating and filtration setups. It accepts rods up to 16.5mm diameter, is listed with a diameter of 16mm, and has a blue coating with well-finished metal edges for safe handling. Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer, producing this bosshead at its own factory in Ambala, India.

Specifications

What Is the Metal Bosshead Used For?

This is the everyday right-angle bosshead of a retort stand lab: one side grips the upright rod, the other holds the shank of a burette clamp, retort clamp or ring so it sticks out horizontally over the bench. In a school titration practical it carries the burette clamp at a comfortable reading height, in a heating experiment it holds a boiling tube or flask over the burner, and in filtration it supports a ring and funnel above a beaker. Because two rods up to 16.5mm are held square to each other, clamps stay level and apparatus hangs straight.

Slide the bosshead to height, tighten it on the stand rod, then insert and lock the clamp. Students handle it often, so the well-finished metal edges matter: there are no sharp burrs to catch fingers. Store bossheads on the rods rather than loose in a drawer so they are ready for the next class.

OEM Manufacturer

ScienceLab is the trade name of Jain Scientific Equipments Private Limited, the OEM that manufactures this blue-coated bosshead at its own licensed factory at Saha, Ambala, Haryana, India. The company is registered as an MSME manufacturer (Udyam UDYAM-HR-01-0003714) and exports under Importer-Exporter Code AAECJ8618A issued by the DGFT.

Bosshead, Swivel (Product Code: SLE/BH/17) is a die-cast zinc connector used to join two support rods at any angle on retort stands in school and college laboratories. Science departments that run angled practicals on many benches choose it because it holds rods up to 16mm and comes in a pack of 25, ready for school lab equipment bulk supply. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Swivel Bosshead Used For?

A swivel bosshead is the joint that lets a stand hold apparatus on a slope. When a whole class assembles the same angled setup — collecting a gas over water with a tilted delivery tube, heating a test tube at a slant, sloping a condenser for a simple distillation, or angling a ramp or mirror in physics — each stand needs a joint that can be set and then locked. A pack of 25 gives every group identical hardware, so the teacher demonstrates once and every bench copies the same angle. It is a small but constant part of chemistry lab equipment in schools across India.

Clamp one side to the stand rod, fit the clamp shank or second rod into the other side, swing it to the required angle and tighten. Recheck the angle after tightening and support glassware by hand while adjusting. Wipe off spills after each lesson and store the bossheads together so the class set stays complete through the year.

What to Specify When Ordering

• The number of packs required — each pack holds 25 swivel bossheads.
• The diameter of your stand rods, since this bosshead takes rods up to 16mm.
• Any stands, clamps or fixed bossheads needed for the same benches, so one quotation covers the full setup.
• The delivery location, in India or abroad.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this swivel bosshead. It is produced at the company's own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, rather than bought in from a trader. Schools, colleges, dealers and importers therefore order class packs straight from the maker, and questions about matching stands, spare fittings or repeat packs go to the manufacturer itself. Read more on the company profile.
