Products
Linear Expansion
A high-quality apparatus to determine precisely co-efficient of expansion of various metals. An aluminium channel carries a 60 cm long metal rod enclosed in a heating jacket having three nipples for water intake, water outlet and thermometer insertion. Dial indicator is a precision instrument sensitive to 0.01 mm/division and is securely mounted. As the apparatus works with hot water, there is no danger from any steam escaping and causing burns on the skin. Complete with four expansion rods of steel, brass, copper and aluminium.
Hook Weight Set Economy
Black Painted weights have a non-movable hook on the top. Bottoms of the weights are recessed and contain a weight below bar allowing weights to be hung from each other. Weight set includes one each of 10 gm, 50 gm, 100 gm, 500 gm and 1Kg. Two each of 20 gm & 200 gm. In plastic molded box.
Led Ray Box
A metal Ray Box comprises a die-cast enclosure and delivers white light but runs much cooler than conventional ray boxes. It uses the latest cool ultra-bright LED technology giving superior white light. Supplied complete with slit plate and battery pack (2 x AA size batteries are not included).
Polarising Filter Stress Determination
Demonstrate stress patterns in solids with this new and valuable equipment. Two polarising filters, mounted on a graduated frame are placed on a plastic base. Clear acrylic pieces of different shapes are introduced between the filters; when pressure is applied to the solids the resulting stress patterns are observed. An important method of demonstrating polarisation and stress. Includes instructions.
Kinetic Theory Model
The Kinetic Theory Model apparatus is used along with the vibration generator to demonstrate the movement of molecules in a gas. An approximate relationship between the floating height, i.e., volume of the gas and weight of the disc, i.e., pressure of the gas can be observed. The platform has a rubber surface and small stainless steel balls are loaded into the tube. With the change in the speed of vibration generator, the heating of the gas stimulates resulting change in the agitation of the balls inside the tube. It comprises theory of piston, steel balls and a base or placing on an overhead projector.
