Bosshead
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.

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.

Frequently Asked Questions
Which versions of the Bosshead are available?
Three versions of the Bosshead (SLE/BH/06) are listed: 18/10 stainless steel with d/Ø 16,5 and thread 8, aluminium with d/Ø 16,5 and thread 8, and a larger aluminium version with d/Ø 27 and thread 10. All share the 180+90 angle.
How do I choose between the stainless steel and aluminium Bosshead?
Pick the 18/10 stainless steel Bosshead for benches exposed to acids, salt solutions and frequent washing; choose an aluminium Bosshead where lighter stands are wanted and strong alkalis are not in use.
What do the two d/Ø sizes of the Bosshead mean?
d/Ø is the catalogued diameter figure of the Bosshead: 16,5 (sixteen and a half, decimal comma) or 27 for the larger aluminium version. Units are not stated in the listing, so send ScienceLab your rod diameter and the right version will be confirmed.
What is the difference between safety screws and ordinary screws on the Bosshead?
The Bosshead is listed with safety screws in heart or thumb style, which are intended to stay captive so they are not lost, and with ordinary heart and thumb screws, which can be removed completely for replacement.
Who manufactures the Bosshead SLE/BH/06?
All three versions of the Bosshead SLE/BH/06 are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its licensed factory in Saha, Ambala, Haryana, India, so stainless and aluminium versions can be quoted together by the maker.
What should a bulk or export enquiry for the Bosshead include?
A bulk or export enquiry for the Bosshead should state code SLE/BH/06, the version (material and d/Ø size), the screw style, the quantity and the destination. ScienceLab supplies India and international markets.
