Retort Clamp Three Finger
Retort Clamp Three Finger (Product Code: SLE/CH/60) is a three-prong clamp that holds round glassware — flasks, condensers, boiling tubes — steady on a support stand while it is heated, filled or connected to other apparatus. Its rubber-covered jaws close around articles up to 75 mm in diameter, which covers most of the glassware handled on school and college chemistry benches. The clamp is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, and is a routine part of any retort stand lab set-up in India and international markets.

Typical Use
Teachers use this clamp to grip the neck of a flask above a burner during heating or simple distillation, to hold a condenser at the right angle, or to steady a boiling tube while a gas is prepared and collected. Because the jaws are driven by a twin screw, both sides close together and the glass stays centred rather than being pushed to one side, which reduces strain on the joint where tubing or a stopper is fitted.
The 15 cm rod is pushed into a boss head on the upright stand rod — the familiar lab stand, clamp and boss head arrangement — so the height and angle can be adjusted before any liquid is added. Tighten the pommels only until the rubber lining just grips; overtightening can crack thin-walled glass, and the rubber should be kept clear of the direct flame.

Frequently Asked Questions
What size of glassware does this clamp hold?
Articles up to 75 mm in diameter. For wider vessels, choose the four finger version.
Can I choose the rod material?
Yes — the clamp is fitted with a 15 cm rod in either mild steel or aluminium. Mention your preference in the enquiry and we will confirm it in the quotation.
Is a boss head part of the clamp?
The listing covers the clamp with its rod. If your stands do not already have spare boss heads, add them to the same enquiry.
Will the jaws mark or crack glass?
The rubber covering cushions the glass, so marking is unlikely. Cracks usually come from overtightening or clamping glass that is still expanding with heat, so tighten gently and recheck after warming.
How should the clamp be looked after?
Wipe off acid or salt spills soon after a practical, dry the screws, and keep solvents away from the rubber lining so it stays soft.
What should a school or college quotation request include?
The quantity, rod material, delivery location and any stands or boss heads needed alongside. Warranty terms are stated in the quotation itself.
Do you supply in bulk or overseas?
Yes. We supply institutions and distributors across India and international markets; contact us with quantities for a delivered quote.
