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.

Who manufactures the Squared Bosshead?
The Squared Bosshead is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as OEM at its licensed factory in the HSIIDC Industrial Area, Saha, Ambala, and is supplied factory-direct to laboratories, dealers and importers.

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.

OEM Manufacturer

This screw is an OEM part: Jain Scientific Equipments Private Limited, trading as ScienceLab, makes it at its own licensed factory at Saha, Ambala, Haryana, India, where the company also manufactures the bosshead range. Laboratories, dealers and importers can order spare screws directly from the manufacturer and ask about fit with the bossheads they already use. Details are on the company profile.

Retort Clamp Standard 18/10 Stainless Steel (Product Code: SLE/RC/01) is a round-jaw laboratory clamp used to hold flasks, tubes and other round apparatus on a retort stand. It is made from 18/10 stainless steel in seven sizes, from 150 mm long with a 10 mm shaft and 25 mm span up to 180 mm long with a 12 mm shaft and 150 mm span. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

Specifications

What Is the Standard Retort Clamp Used For?

A standard retort clamp grips a flask, condenser, test tube or column so it stays steady above a burner or over a collecting vessel. Its shaft locks into a bosshead on a vertical support rod, and the round jaws close around the neck or body of the apparatus. Matching the span to the vessel matters: the 25–60 mm spans suit test tubes and flask necks, while the 80–150 mm spans take larger flasks and columns.

The 18/10 grade of stainless steel is corrosion-resistant and wipes clean after spills, so this clamp is a practical choice for teaching labs, research benches and any chemistry lab equipment set that sees daily use. Tighten the jaws only until the glassware is held firmly, because over-tightening metal jaws can crack glass. Where glass is thin-walled, a strip of rubber or cloth between jaw and vessel spreads the pressure.

What to Specify When Ordering

• Span d — choose 25, 40, 60, 80, 100, 120 or 150 mm to fit the diameter of your apparatus.
• Shaft diameter — the 150 mm clamps have a 10 mm shaft and the 180 mm clamps a 12 mm shaft; check that your bossheads accept it.
• Quantity per size — most labs mix small and large spans, so state the number needed of each.
• Stand parts — add bossheads and stand bases from the list below if you are equipping new stands.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the original equipment manufacturer (OEM) of this stainless steel retort clamp and makes the full size range at its own licensed factory at Saha, Ambala, Haryana, India. Because the clamps come direct from the factory, laboratories, colleges, distributors and importers in India and international markets can mix sizes in one order and deal with the maker for repeat supplies. Ask us about replacement parts for clamps already in service. More about the company is on the ScienceLab profile page.

Retort Clamp Special 3-Prongs, 18/10-Stainless Steel (Product Code: SLE/RC/02) is a three-finger laboratory clamp used to hold glassware of different diameters on a support stand. Its stainless steel fingers carry a silicone coating that cushions the glass, and it comes 190 mm long on a 12 mm shaft with a span of 0–80 mm or 0–120 mm. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the 3-Prong Special Retort Clamp Used For?

Three fingers close on an object from three directions, centring round-bottom flasks, separating funnels, condensers and columns more naturally than a two-jaw clamp. Because the span opens from zero, the 0–80 mm version holds slim tubes as well as medium flasks, while the 0–120 mm version reaches wider vessels. That range lets one clamp serve many setups in chemistry lab glassware work, from distillation to filtration.

The silicone coating on each finger grips without scratching and spreads the load on glass, cushioning it without extra padding. Mount the 12 mm shaft in a bosshead, position the clamp before tightening, and check that the vessel hangs straight before adding liquid or heat. Keep the coated fingers away from direct flame.

What to Specify When Ordering

• Span version — 0–80 mm or 0–120 mm, based on the widest vessel you need to hold.
• Quantity — the number of clamps per bench or per stand.
• Bossheads — confirm that yours accept a 12 mm shaft, or add stainless bossheads to the order.

OEM Manufacturer

This 3-prong clamp comes from ScienceLab, the trade name of Jain Scientific Equipments Private Limited, which is its OEM and produces it at the company's own licensed factory at Saha, Ambala, Haryana, India. Research laboratories, universities, schools, dealers and importers in India and international markets buy it direct from the manufacturer rather than through a trading house.

Why are the fingers of this 3-prong clamp silicone coated?
The fingers of the Retort Clamp Special 3-Prongs carry a silicone coating so they grip glassware firmly without metal-to-glass contact, which helps prevent scratches and spreads the pressure on thin-walled flasks and tubes.

How does the 3-prong special clamp differ from a standard retort clamp?
The Retort Clamp Special 3-Prongs uses three silicone-coated fingers that centre round vessels and open from zero, whereas a standard retort clamp has bare round jaws in fixed span sizes. The 3-prong design suits mixed diameters on one stand.

It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

Specifications

What Is the 3 Prong Retort Clamp Used For?

This clamp holds round apparatus such as flasks, test tubes and small columns steady on a retort stand during titration, filtration and demonstration setups. Because each regulating screw adjusts independently, the span can be set so that an off-centre or unevenly shaped item is gripped evenly, and the clamp can sit exactly where the vessel needs support.

The red PVC finish makes the clamp easy to spot on a crowded bench, a small but real help in busy practical classes, and it is an everyday piece of chemistry lab equipment in schools. As a PVC item, it should be kept clear of burner flames and hot plates; for heated work choose a stainless steel clamp instead. Tighten both screws evenly and check the hold before letting go of the vessel.

What to Specify When Ordering

• Quantity — the number of clamps needed per stand or per bench.
• Vessel sizes — share the diameters you need to hold so we can confirm them against the listed 12–100 mm range.
• Stand parts — add a stand base or other clamps from the list below if you are setting up new stations.

Retort Clamp Special 4-Prongs (Product Code: SLE/RC/05) is a four-finger stainless steel laboratory clamp used to hold larger or heavier round vessels, such as big flasks and wide columns, firmly on a retort stand. Made from 18/10 stainless steel with silicone-coated fingers and a 12 mm shaft, it comes in three sizes with spans of 0–120 mm, 20–100 mm or 50–150 mm. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM, at its own factory in Ambala, India.

Specifications

What Is the 4-Prong Special Retort Clamp Used For?

A fourth finger spreads the holding force around more of the vessel, so the clamp resists tilting when it carries a large round-bottom flask, a wide chromatography column or a full separating funnel. The 150 mm size with a 0–120 mm span covers everything from narrow necks to mid-sized bodies, while the two 190 mm sizes reach further from the rod and are set for mid-range (20–100 mm) or wide (50–150 mm) vessels.

Silicone-coated fingers keep metal off the glass and add grip on smooth surfaces. For heavy loads, mount the clamp low on the support rod, tighten the bosshead fully before adding liquid, and keep the coated fingers clear of direct flame. Checking the stand for wobble before starting a long run is a good habit in any teaching or research lab.

What to Specify When Ordering

• Size — 150 mm with 0–120 mm span, 190 mm with 20–100 mm span, or 190 mm with 50–150 mm span.
• Vessel range — note the smallest and largest diameters you need to hold.
• Bossheads — confirm that they accept a 12 mm shaft.
• Quantity — the number required of each size.
