Leslie’s Cube
Catalogue No: 1061080/2
Useful for qualitative activities in thermal radiation. The results can also be quantified using a suitable radiation sensor facilitating investigation of emission and absorption of radiation from different surfaces at a same temperature or radiation from a single surface at different temperatures (Stefan-Boltzman’s Law). Comprises a sheet metal cube of sides about 130mm with opening at the top for pouring in water and inserting a thermometer through a holed rubber stopper. Each of the four vertical faces is finished black, varnished, roughened and polished.

Linear Expansion Apparatus, Micrometer Type
Catalogue No: 1060220
Comprises of an epoxy coated metal tube having a riffled nozzles near each end, for use as inlet and outlet of steam and another tubule at the center with holed rubber bung for inserting thermometer to measure the inside temperature. Metal tube is mounted horizontally on the metal base with the help of brackets, with one end having a precision micrometer screw head reading to 0.01mm and other end having adjusting screw. The metal rod to be investigated is supported in the steam jacket by detachable conical cups situated at each end of the tube. Supplied complete with metal rods, one each of copper, brass and Aluminum rods but without thermometer.

Linear Expansion Apparatus, Precision, Dial Type
Catalogue No: 1060240
The Accuracy +-n determination of coefficient of linear expansion of the material of a rod depends on the precision in the measurement of the expansion produced, which is provided by a dial gauge indicator, graduated 0.01mm per division. Ideal for higher grade students. The expansion rod is located in a metal tube and is heated by means of steam inlet to the tube. It requires no electrical terminals or accessories for measurement. The apparatus comes completely assembled and includes four expansion rods. (One each of steel, brass, copper and aluminum.)

Linear Expansion Apparatus, Simple
Catalogue No: 1060160
Demonstrates the linear expansion of solids and allows comparison of thermal expansion of rods of different materials. A horizontal metal reservoir to take liquid fuel is mounted on a pair of cast metal supports. The apparatus also has pointer scale to indicate expansion in the rod. Burning of the heat causes rod above it to expand. Includes three expansion rods, one each of brass MS and aluminum.

Melting Point Apparatus, Simple
Catalogue No: 1060620
A simple device for determination of melting point of amorphous solids. Comprises an Aluminum cylinder with an obliquely drilled hole at its top for accommodating thermometer. When a very thin layer of the substance, whose melting point is to be determined, is sprinkled on top of the block and is gently heated, the temperature at which substance melts can be directly read from the thermometer.

Radiation Absorption Discs
Catalogue No: 1060395
The four aluminum discs with tough anodized surfaces of mirror silver, mirror black, matt silver and matt black have dramatically different properties. Each disc has a 30-60 degree liquid crystal thermometer bonded to them, showing clearly how surface color and texture affects the absorption and reflection of radiant heat. These discs are perfect for rapid are repeatable results for experiment with infrared absorption.

Ring and Ball
Catalogue No: 1060020/3
A simple and economical device for demonstrating the thermal expansion of solids. Comprises an annular brass ring mounted on an insulated handle and a captive brass ball secured to the ring handle through a chain and having diameter just smaller than the internal diameter of the ring. When cold, the ball easily passes through the ring but does not pass on heating. Both ring and ball when heated to the same extent, the ball still passes through the ring showing the expansion of a hole effect. Available in ball diameters:
