Three Prong Glassware Holding Clamp

Product Code : SCL-CL-12015

Three Prong Glassware Holding Clamp (SKU SCL-CL-12015) is a three-finger extension clamp that holds round-bottom flasks, condensers, funnels and tubes on a retort stand with three points of contact. It is the everyday clamp of school and college chemistry benches and is also used in physics and biology set-ups. Science Lab Supplies, a chemistry lab instruments supplier in Ambala, India, provides it to schools, colleges, training institutes, tender contractors and distributors.

Specifications

A die-cast zinc-aluminium alloy head with a powder-coated finish sits on a 200 mm grade 304 stainless steel rod of 10 mm diameter. Two threaded thumbscrews adjust the jaws independently from 15 mm to 85 mm, and heat-resistant vinyl sleeves on the prongs prevent glass-to-metal contact.

Applications and Experiments for the Three Prong Clamp

A three prong clamp holds glassware steady above a burner or mantle, or over a collecting vessel. It is used in Class 11–12 chemistry for distillation, filtration and gas preparation, in B.Sc. organic chemistry for reflux and distillation, and in pharmacy and diploma laboratories for routine glassware support.

• Holding a round-bottom or distillation flask over a heat source.
• Supporting a condenser at an angle in a distillation set-up.
• Holding a separating funnel during solvent extraction.
• Clamping a boiling tube or thermometer in heating and cooling-curve experiments.

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. The listed pack includes four replacement vinyl prong sleeves, so worn or damaged sleeves can be changed without replacing the clamp.

Who supplies the Three Prong Glassware Holding Clamp?
The clamp comes from Science Lab Supplies in Ambala, India, which supplies laboratory hardware and glassware to institutions and dealers and quotes to them directly.

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.
