What Is a Boss Clamp Used For?
A retort stand on its own is only a base and an upright rod; the boss clamp is what turns it into a frame. One jaw grips the upright rod and the other grips the shank of a clamp, a ring or a cross rod, and each screw is tightened separately, so the attachment can be set at any height and swung to any angle. Typical set-ups include a flask held over a burner for heating, a condenser clamped at a slope for distillation, a funnel held above a beaker for filtration, and a ring with wire gauze for evaporating a solution — work found in class 9 to class 12 science and chemistry practicals and in college labs.
Aluminium alloy is light and does not rust, and the brass screws are nickel plated, so the clamp suits labs where water and dilute solutions are splashed about. Tighten the screws by hand only, keep the threads free of dried chemical, and wipe the clamp after use. When clamping heavy glassware, turn the attachment so the load sits over the stand’s base, which keeps the stand from tipping.
What to Specify When Ordering
- Rod diameters — give the diameter of your stand rods and clamp shanks so the fit can be confirmed.
- Quantity — most set-ups use one boss clamp per clamp or ring, and many need two; the minimum order is 10 units.
- Clamps and rods — add retort clamps, burette clamps and stand rods to the same enquiry to complete each bench.
Frequently Asked Questions
What is the boss clamp made of?
The body is pressure die-cast aluminium alloy, and the clamping screws are nickel-plated brass.
What rod diameter does it take?
The listing does not give a rod size. Send the diameters of your stand rods and clamp shanks and JLab will confirm the fit in its quotation.
What do the offset jaws do?
They grip the upright rod and the clamp shank in two separate jaws, so the two rods cross at an angle and each can be tightened on its own. If the exact jaw layout matters for your set-up, ask JLab for a photograph.
How is it different from the zinc alloy boss head?
The material and the jaw design. This clamp is aluminium alloy with offset jaws and brass screws, while the Boss Head listing is zinc alloy with plated screws and a stated rod limit of 16 mm.
Are clamps or rods included?
No, this listing covers the boss clamp only. Retort clamps, burette clamps and stand rods are separate items.
What is the minimum order and dispatch lead time?
The minimum order is 10 units, sold individually. Orders usually leave within 7–10 working days after each clamp is visually inspected, and export transit time depends on the destination and shipping method.
Who manufactures this boss clamp?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, and quotes for it directly.
