- Holding a round-bottom flask or a Distillation Flask over a heat source.
- Supporting a condenser such as the 450 mm Liebig Condenser for Distillation of Water at an angle.
- Holding a separating funnel during solvent extraction.
- Clamping a boiling tube, or one of the alcohol-filled Laboratory Thermometers, in heating and cooling-curve experiments.
Standard Scope of Supply
The pack includes two three prong clamp units, four heat-resistant replacement vinyl prong sleeves and an apparatus mounting and safety leaflet. Stands, boss heads and glassware are separate lines that can be added to the same quotation when a full bench is being set up.

Frequently Asked Questions
When should I choose a three prong clamp over a four prong clamp?
Both open from 15 mm to 85 mm on a 200 mm rod. The three prong type is the general choice for round flasks, condensers and funnels; the four prong type spreads the grip over four fingers for large or irregular vessels.
Are spare prong sleeves supplied?
Yes. Each pack of two clamps includes four heat-resistant replacement vinyl prong sleeves, so worn or damaged sleeves can be changed without replacing the clamp itself.
Who supplies the Three Prong Glassware Holding Clamp?
It comes from Science Lab Supplies in Ambala, India, which sends quotations for laboratory hardware and glassware straight to institutions and dealers. The clamps can be priced together with stands and boss heads in the same reply.
Is the clamp safe to use near a flame?
Keep the vinyl-covered prongs clear of the flame itself and hold hot vessels by the neck. Heating work should be done under teacher or technician supervision.
