Charles Law Apparatus Manufacturer,Supplier and Exporter in India
Product Code : EL-PLE-10297
Lab Instruments Manufacturers manufactures the Charles' Law Apparatus in-house at our own India facility, supplying it to physics laboratories in schools and colleges, and as an OEM/private-label item to distributors and exporters across India and internationally.
What This Apparatus Does
This apparatus consists of a glass U-tube, with a bulb and tap at the upper end of one limb and the other limb left open. From the bottom of the U-tube, an outlet tube passes through a bung and terminates in a tap. The bulb has a capacity of 7cm³, and the graduated stem beneath it is marked in divisions of 3×0.1cm³, allowing gas expansion to be read over a temperature range of 100°C. The apparatus can be supported on a single clamp.

Typical Use
School and college physics laboratories use this apparatus to demonstrate Charles' Law, the expansion of a gas with temperature at constant pressure, reading the change in gas volume against the graduated stem as temperature rises.
Manufactured In-House
This apparatus is manufactured at our own India production facility. Manufacturing in-house means our team controls the bulb and stem calibration at every stage, and can produce custom sizes or bulk sets for a specific institutional order or export shipment without waiting on an outside supplier.
Frequently Asked Questions
