Calorimeter Lagging
Calorimeter Lagging (Product Code: SCI-1457/021) is a thick felt insulating jacket used to cut heat exchange between a calorimeter and the room during heat experiments in school and college laboratories. It fits copper and aluminium calorimeters of 50 mm, 65 mm or 75 mm diameter and comes with a felt mat that insulates the base. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is Calorimeter Lagging Used For?
Every method-of-mixtures or specific heat experiment assumes that the heat lost by the hot body is gained by the water and the calorimeter, not by the air. A bare metal calorimeter leaks heat through its walls and base, which pulls the final temperature away from the true value. Wrapping the vessel in felt lagging and standing it on the felt mat slows that loss, so results for specific heat capacity or latent heat come closer to textbook values.
Slide the jacket over the calorimeter before adding water, keep the felt dry, and read the thermometer promptly once the mixture settles. The lagging turns a basic vessel into a more complete calorimeter experiment kit and is a sensible spare for any calorimeter lab in India that runs heat practicals every term.
What to Specify When Ordering
- The calorimeter diameter each jacket must fit: 50 mm, 65 mm or 75 mm.
- Whether your calorimeters are copper or aluminium.
- The number of jackets needed per diameter, usually one per student group.
- Whether you also need calorimeters or thermometers on the same order.
OEM Manufacturer
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer of this felt lagging. The jackets are made at the company's own licensed factory in Saha, Ambala, in the three calorimeter diameters listed above. Institutions, dealers and importers order factory-direct, and repeat orders for extra jackets go straight to the maker. About ScienceLab.

Frequently Asked Questions
What sizes of Calorimeter Lagging are available?
Calorimeter Lagging is made for calorimeters of 50 mm, 65 mm and 75 mm diameter. Tell us which diameter you use, and how many of each, so the felt jacket fits the vessel snugly and insulates it properly.
What is included with the Calorimeter Lagging?
The Calorimeter Lagging consists of a thick felt jacket for the side of the calorimeter plus a felt mat for insulating the bottom. Together they wrap both the walls and the base, the two places a bare calorimeter loses most heat.
Does Calorimeter Lagging fit copper and aluminium calorimeters?
Yes, Calorimeter Lagging is intended for both copper and aluminium calorimeters. What matters for the fit is the vessel diameter, so choose the 50 mm, 65 mm or 75 mm jacket that matches your calorimeter.
Why should a calorimeter be lagged?
Lagging a calorimeter reduces heat exchange with the surroundings, so the heat balance in a method-of-mixtures experiment stays closer to ideal. Calorimeter Lagging therefore helps students obtain more consistent values for specific heat capacity and latent heat.
Who manufactures the Calorimeter Lagging?
The Calorimeter Lagging is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Ambala, Haryana, India. Schools, colleges, dealers and importers buy it factory-direct, with quotations issued by the manufacturer itself.
Can Calorimeter Lagging be ordered in bulk?
Yes, Calorimeter Lagging can be quoted in quantity for schools, colleges, tenders and dealers in India and international markets. Share the diameters and number of jackets required, and we will prepare a quotation covering the complete order.
