Joules Calorimeter, Fully Assembled, 6 ohms, Each

Joule’s Calorimeter is designed for conducting the electrical method of determining the specific heat capacity of a liquid. It is a valuable tool for professional laboratories, science classrooms, and home-based experiments.

Calorimeter Construction

The calorimeter consists of a nickel-plated copper vessel, measuring 76mm in height and 51mm in diameter. This inner vessel is lagged for insulation and enclosed within an outer container measuring 102mm in height and 70mm in diameter, reducing heat loss during experiments.

Lid & Stirring Mechanism

A close-fitting ebonite lid is included, featuring a built-in wire stirrer. This ensures uniform heat distribution throughout the liquid sample, improving measurement accuracy.

Electrical Components & Resistance

The calorimeter is equipped with a pair of 4mm socket terminals, which connect to a constantan wire heating coil. The coil has a resistance of approximately 6 ohms and operates effectively with a current of 0.5A, with a maximum limit of 1A. The power supply is not included.

How to Avoid Corrosion

• Thoroughly dry the vessel after cleaning to prevent moisture-induced copper corrosion.
• Store the vessel in a cool, dry area with low humidity.
• For extra protection, wrap the vessel in a sealed plastic bag with silica gel packets to absorb residual moisture

DISCLAIMER! Breaches in the nickel plating may still pose a challenge in fully preventing corrosion.
