Calorimeter Blocks Manufacturer,Supplier and Exporter in India

Product Code : EL-SLE-5777
Jlab Export is a leading Calorimeter Blocks Manufacturer,and suppliers in India

Calorimeter Blocks (code EL-SLE-5777) are nickel-plated aluminium alloy blocks, 75 mm in diameter, for measuring the specific heat capacity of a metal by electrical heating in school and college physics labs. Each block is drilled to take a thermometer and an immersion heater, and the listing names a 12 V DC, 50 W heater made to fit it. They are made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

Specifications

How Does It Compare with Other JLab Calorimeter Blocks?

Choose this block when one aluminium alloy block with its own 12 V DC heater is enough for the electrical method. The Heater Block Calorimeter set suits classes that want to compare several metals using blocks listed at the same mass.

What Is the Calorimeter Block Used For?

A calorimeter block is the usual apparatus for the electrical method of finding specific heat capacity — the energy needed to raise the temperature of one kilogram of a material by one kelvin. The immersion heater goes into one hole and a thermometer into the other. The energy supplied is worked out from the heater voltage, current and heating time, or read directly from a joulemeter, and the specific heat capacity is that energy divided by the mass of the block multiplied by its temperature rise. The experiment supports class 11 teaching on thermal properties of matter, secondary physics practicals in many international syllabuses, and first-year college heat labs.

Weigh the block before you start, because its mass goes into the calculation. A few drops of oil or water in the thermometer hole improve thermal contact, and wrapping the block in an insulating jacket such as cotton wool or expanded polystyrene reduces heat loss to the room. Switch the heater on only when it is fully seated in the block, record the temperature at regular intervals, and note the highest reading after switching off, since the temperature keeps rising briefly. Let the block cool before handling it.

What to Specify When Ordering

• Quantity — the minimum order is 10 blocks.
• Immersion heater — confirm that you need the 12 V DC, 50 W heater with each block, and how many spares.
• Measuring items — thermometers, a low-voltage DC supply and a joulemeter or ammeter and voltmeter are separate catalogue items; add them to the same enquiry.
• Block mass — if your worksheets assume a particular mass, ask for the nominal mass and height of the block with the quote.

Frequently Asked Questions

What is the calorimeter block used for?
Measuring the specific heat capacity of the aluminium alloy block by electrical heating. The heater warms the block, the thermometer shows the temperature rise, and the energy supplied divided by mass times temperature rise gives the result.

Which heater does the block take?
The listing specifies a 12 V DC, 50 W immersion heater made to fit the calorimeter block. Run it from a suitable low-voltage DC supply, and state in your enquiry whether you want a heater supplied with every block.

What is the mass of the block?
It is not stated in this listing. Weigh each block on a laboratory balance before the experiment, as the measured mass is used in the calculation, or ask JLab for the nominal mass when you request a quotation.

How does it differ from the Heater Block Calorimeter?
This listing is a nickel-plated aluminium alloy block, 75 mm in diameter, with a 12 V DC, 50 W heater. The Heater Block Calorimeter is listed as cylindrical 1 kg blocks in aluminium, brass, copper and steel, each with separate heater and thermometer holes, for comparing metals.

Is a thermometer included?
No thermometer is part of this listing. The block is drilled to accept one, and laboratory thermometers are separate items that can be added to the same enquiry.

What details are needed for an export quotation?
The quantity, the destination country and port or city, delivery terms such as FOB or CIF, any packing or labelling needs, and the tender reference if the purchase is for a tender.

Who manufactures these calorimeter blocks?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes them at its works in Ambala, Haryana, India, and quotes for them directly as the manufacturer.

OEM Manufacturer

JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of school physics apparatus and laboratory equipment in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. The calorimeter blocks are made at JLab’s own works rather than sourced from a trader, so schools, colleges, dealers and importers deal with the factory directly; every block is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Algeria in North Africa, El Salvador in Central America and the Caribbean, the USA in North America, Iceland in Northern Europe and Tajikistan in Central Asia. Institutions buying by tender can find details on the JLab lab tenders page.
