Four Prong Laboratory Clamp
.jpg)
Product Code : SCL-CL-12014
Four Prong Laboratory Clamp (SKU SCL-CL-12014), also called a four-finger clamp, holds large, tapered or irregular glass vessels on a retort stand. Its two pairs of fingers are adjusted separately, so it centres on wide-necked flasks, columns and condensers that a two-jaw clamp grips poorly. Chemistry teachers, lab technicians and college practical staff use it for distillation and extraction work. Science Lab Supplies, Ambala, India, supplies it to schools, colleges, training institutes, contractors and distributors.
Specifications
The clamp head is die-cast zinc or aluminium alloy with a powder-coated finish, fixed to a 200 mm stainless steel extension rod of 10 mm diameter. Two threaded steel thumbscrews each move one pair of PVC-sleeved fingers, giving a jaw opening from 15 mm to 85 mm.

Applications and Experiments for the Four Prong Laboratory Clamp
The clamp is chosen when a vessel is too wide or too awkwardly shaped for a standard clamp. It supports condensers and flasks in distillation, extraction columns and large separating funnels, and appears in Class 11–12 purification practicals, B.Sc. and M.Sc. organic chemistry labs and pharmacy college laboratories.
- Holding Liebig or Allihn condensers in simple and fractional distillation set-ups.
- Supporting Soxhlet extractors and reaction columns above a heating mantle.
- Gripping wide-necked flasks and separating funnels during solvent extraction.
The vinyl sleeves keep metal off the glass and cushion a hot vessel as it expands; tighten the thumbscrews only until the vessel is held firmly.
Standard Scope of Supply
According to the product description, the pack contains two heavy-duty four-finger clamp units, four replacement vinyl finger sleeves and an apparatus set-up and alignment guide. A boss head is needed to fix the clamp to a stand and is quoted separately.
Packing, MOQ and Lead Time
Ask for one pack or a quantity for every distillation bench in the lab. The quotation sets out the packing, delivery time and price for that quantity, and boss heads, stands or other laboratory distillation apparatus in India can be quoted with it.

Frequently Asked Questions
What is the difference between a four prong and a three prong clamp?
Both open from 15 mm to 85 mm on a 200 mm rod. The four prong model grips with four fingers in two adjustable pairs, which spreads the pressure on large or tapered vessels; the three prong model holds with three points of contact.
How do I attach it to a retort stand?
Slide the 10 mm extension rod into a boss head fixed on the stand rod, set the height and angle, then tighten the boss head thumbscrew.
Who supplies the Four Prong Laboratory Clamp?
Science Lab Supplies supplies this clamp from Ambala, India. Laboratories, colleges and dealers get their quotation directly from the Ambala team, together with any stands or glassware on the same list.
