What Is the Extension Clamp Used For?
An extension clamp reaches out from the upright rod of a retort stand and grips a piece of apparatus so that it stays steady while the experiment runs. Three prongs close around a round neck or body from three sides, which makes this type well suited to flasks, condensers, measuring cylinders and wide tubes in distillation, gas-preparation and heating set-ups. The stainless steel rod resists rusting on a wet bench, and the PVC sleeves reduce the risk of the glass slipping or being scratched. It is everyday retort stand equipment for class 11 and 12 chemistry practicals and for college and research laboratories.

- Quantity of clamps — for example one or two per retort stand.

Frequently Asked Questions
What is the extension clamp made of?
The rod is stainless steel and the three prongs carry non-slip PVC sleeves.
How is an extension clamp fixed to a retort stand?
Extension clamps are normally held on the stand rod with a boss head. JLab makes boss heads as separate items, which can be quoted on the same enquiry.
How does it differ from the Aluminium Universal Clamp?
This clamp has three prongs, a stainless steel rod and PVC sleeves. The Aluminium Universal Clamp is two-pronged sheet metal with spring-controlled, cork-lined curved jaws.
Who manufactures this extension clamp?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The extension clamp is made at JLab’s own works rather than sourced from a trader, so schools, colleges, dealers and importers buy it from the maker, and each clamp is checked visually before dispatch. JLab exports worldwide and ships to buyers in every region — Greece in Southern Europe, Gambia in West Africa, Tajikistan in Central Asia, Gabon in Central Africa and Iceland in Northern Europe are a few examples.
