Choose the wooden model when you want a copper calorimeter in a solid teak casing with a Bakelite lid. The Joules Calorimeter is listed with its constantan heating coil and socket terminals fitted in the lid, the set uses a resistor heater with foam insulation, and the double-wall aluminium calorimeter has no heater listed, for experiments that do not need electrical heating.
What Is the Wooden Joule Calorimeter Used For?
A Joule calorimeter turns electrical energy into heat inside a known mass of liquid. Students pass a steady current through the heater for a measured time, note the voltage and current, and record the rise in temperature; the electrical energy supplied (V × I × t) is then compared with the heat taken up by the liquid and the copper vessel. The result gives the specific heat capacity of the liquid, or the mechanical equivalent of heat (J) in syllabuses that still include it, and it shows Joule’s law of heating from the electricity chapters of school physics.
Weigh the empty copper vessel first, fill it with a measured quantity of liquid, stir gently between readings and keep the current steady. Copper conducts heat well, so the vessel and liquid stay at the same temperature.
What to Specify When Ordering
- Quantity — the minimum order is 10 calorimeters.
- Thermometer and stirrer — the lid takes both; ask whether they are supplied with the calorimeter or add them to the enquiry.
- Heating circuit — the power supply, ammeter, voltmeter and rheostat are not part of this listing; add them if you need a complete set-up.
Frequently Asked Questions
What is the Wooden Joule Calorimeter used for?
Heat experiments with electrical heating, such as finding the specific heat capacity of a liquid or the mechanical equivalent of heat in school and college physics practicals.
What are its dimensions?
The calorimeter is listed as 3 in x 2 in (about 76 x 51 mm), and the teak wood outer box measures 9.5 x 9.5 x 11.5 cm.
Why is the outer vessel made of teak wood?
Wood is a poor conductor of heat, so the box, together with the Bakelite lid, reduces heat loss from the copper vessel during a run and makes the temperature readings more reliable.
Are the thermometer, stirrer and power supply included?
The listing does not say so. The Bakelite lid has holes for a thermometer and a stirrer; confirm in your enquiry whether you need them supplied, and order the power supply and meters separately.
How does it differ from the Joules Calorimeter?
Both have a copper vessel of similar size. The Joules Calorimeter is listed as nickel-plated, lagged inside an outer vessel, with an ebonite lid carrying a wire stirrer, socket terminals and a constantan heating coil; this model uses a teak wood box and a Bakelite lid.
Who manufactures it?
Jain Laboratory Instruments Pvt Ltd (JLab) makes this calorimeter at its works in Ambala, Haryana, India, and quotes for it directly as the manufacturer.
OEM Manufacturer
Jain Laboratory Instruments Pvt Ltd, trading as JLab, is a physics and science laboratory equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The wooden Joule calorimeter is built at its own works instead of being sourced from a trader, so schools, colleges, dealers and importers buy it factory-direct, every unit is inspected by eye before dispatch, and repeat orders are handled by the same maker. JLab exports worldwide and ships to buyers in every region — Finland in Northern Europe, Fiji in Oceania, Bulgaria in Eastern Europe, Mexico in North America and Eswatini in Southern Africa are a few examples. For institutional purchasing, see the JLab lab tenders page.
