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.

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.

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.

It is listed with d/Ø 13,5, a 90° angle and thread 6, with a ring or socket screw, and suits chemistry labs where glass trains stay assembled. The maker is Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer producing it at its own factory in Ambala, India.

Specifications

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.

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

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.
• Number of connectors for each frame, plus spares.
• Frames, stands or clamps you want in the same quotation.

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.

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.
