Consisting of a brass disc about 15cm in diameter, 6 mm thickness, with arrangement for clamping a split chuck. Supplied with wall bracket.

It consists of an aluminum disc of approximately 6" dia with a groove. The circular aluminum disc supports five semicircular masses which just fit into a groove, concentric with the circumference. It can be suspended by a steel wire pivoted at the centre of a long frame work, provided with circular base which is also fitted with leveling screws. Supplied with four different shapes of masses (Rectangular, Square, circular and triangular.)

It consists of a solid brass rod of length 30cm and diameter 1.5cm with centre split chuck for clamping and suspending. Supplied without wall bracket.

This method is suitable for the purpose of studying the variation of surface tension, with concentration of solution of common salt in water. Complete with manometer tube fitted on the stand, conical flask with side tube, dropping funnel, three different bore jets and beaker etc.

Specifications are same as above cat no. 1097 but it consists of brass or stainless rod instead of steel C.P. rod. Two metal weights are also made of brass instead of cast iron. Other specifications are same as above.

It is a compound pendulum constructed on the principle that centre of oscillation and centre of suspension are interchangeable. It consists of a steel rod of l20cm long and 1.0 cm dia capable of two adjustable knife edges facing each other. Two metal weights (made of cast iron) of dimension 7.5 x 3.75cm (length x diameter) and (3.5 x 3.75) respectively can be made to slide along the length of the bar and can be clamped in any position. Two wooden weights exactly similar to metal weights can also slide along the bar. With the help of this apparatus we can find acceleration due to gravity at a place.

This stand is suitable for all types of compound pendulums or Kater's pendulums cat no. 1097 listed above. Heavy type stands having approx. height 52 inches.

A glass tube 100 cm long and 3.8 cm in diameter.fited on a base. A rod about 60 cm long is held firmly at its mid point in a sturdy clamp at one end of the base. One end of the rod has a metal disc attached to it and projects into the glass tube. The other end of the tube is closed by a close fitting piston mounted on the base such that its position in the tube is adjustable through 20 cm approx..

A glass tube 100 cm long and 3.8 cm in diameter is mounted in a ‘Y’ on a metal base .A rod about 60 cm long is held firmly at its mid point in a sturdy clamp at one end of the base . One end of the rod has a metal dics attached to it and project into the glass tube. The other end of the tube is closed fitting piston mounted on the base such that its position in the tube is adjustable through 20 cm. app. The ‘Y’ supporting the tube may be adjusted vertically and laterally untill the metal disc will not touch the glass. Coiled spring attached to the ‘Y’ holds the glass tube in position.
