Absolute Expansion of Mercury Apparatus, Dulong & Petit
To determine the co-efficient of absolute expansion of mercury. Glass tubes with vertical limbs contained within glass jackets approx. 460 x 25 mm height x diameter, are closed by bungs and fitted with inlet and outlet tubes. Upper ends of these vertical limbs are angled on emergence from the jackets to produce two short, adjacent limbs placed against a silvered glass scale 0 to 12 cm x 1 mm. Mounted on stand 610 x 230 mm, height x width. Overall height 750 mm approx., supplied without mercury.

Charle’s Law Apparatus
To determine the coefficient of expansion of a gas at constant pressure. A glass U-tube with a bulb and stopcock at one end, the other limb being open. An outlet tube from the bottom of the U tube passes through a rubber bung and has a stopcock at the end. The stem below the bulb is graduated 3 x 0.1 ml. An inlet tube with a mohr clip also passes through the bung. A glass water jacket encloses the U tube. All glass parts made of borosilicate glass require only 20 ml mercury, which is not included.

Charle’s Law Kit
A glass U-tube of 10 mm diameter the shorter limb of which has a stopcock near top and the longer limb can take a plastic tube. A scale is provided and can be attached to the shorter limb. With red indicator oil but without 2000 ml tall form beaker which acts as a reservoir.

Ice Melting Kit
Demonstrates the difference in thermal conductivity of two different materials. The kit consists of two identical blocks, one made of aluminum and other made of plastic. When an ice cube is placed on aluminum it turns into water in seconds, while on plastic block, it melts slowly. The aluminum block has a larger heat capacity and a higher thermal conductivity, while the plastic block has lower values of both parameters. With instructions.

Aneroid Calorimeter
This calorimeter features an advanced insulated outer wall that delivers nearly five times the sensitivity of standard models. The central chamber is made of aluminum and is fully enclosed within a thick Styrofoam insulation layer; all housed inside a strong plastic casing to minimize heat transfer and ensure very low heat loss during experiments. Key features include:
- Aluminum inner chamber for accurate thermal measurement
- Multi-layer insulation with Styrofoam for superior heat retention
- Robust plastic exterior for added durability and reduced heat flow
- Compatibility with specific heat cylinder sets for thermal property studies
Accessories (Not included): Specific Heat Cylinders Set (PH20183)

Immersion Heater
Specially designed for metal block calorimeters. The heating element is enclosed in a stainless-steel tube with two connecting leads, insulated with heat-resistant insulation. The stainless-steel enclosure features a sealed base to prevent water leakage and a threaded cap at the opposite end for the insertion of a porcelain pipe. Rated at 12 V, 50 W.
