Made of plastic medium size for class demonstration with spout for specific gravity experiments.

Also known as Mariotte's Cylinder, this simple device offers a famous and convincing demonstration of the increase in water pressure with depth. The cylinder has three equally spaced holes in its sides. When the cylinder is filled with water, the outflowing streams follow three different trajectories, governed by the water pressure at the depth of each hole. Made of Sheet Metal cylinder 400 x 60 mm (h x d) with a wide base ensure stability.

This set of five borosilicate glass tubes of different shapes are connected together to illustrate that liquids will stand at the same level. The five glass tubes are sealed to a manifold and mounted on a polished wooden support

A working model of a clear glass to show and explain the principle involved. It has a cylinder of 25 mm dia and overall lengths of 350 mm. Cylinder is provided with non-return float valves and outlet is by means of a side tube. Glass part mounted on wooden stand.

A working model to demonstrate the principles involved in the action of a force-pump. Cylinder is 25 x 350 mm dia x overall height. It is provided with a non-return float valve at its lower end. Lower part of the cylinder has an outlet side tube communicating with the lower end of another cylinder also equipped with non-return valve. Outlet tube from the secondary cylinder is drawn out into a jet to demonstrate ability of force pump to eject water at high pressure. Mounted on wooden stand.

The apparatus comprises a pumping cylinder dia 25mm x 350mm overall height, provided with a piston and a non return valve at its lower end. A side tube joined at lower end of cylinder is also provided with a non return valve as shown in the picture.

To show that pressure of a liquid is transmitted equally in all directions A glass cylinder approximately 200 x 25 mm provided with plunger terminating in a spherical bulb 50 mm diameter, the spherical bulb having a series of a small holes along its circumference.

Comprising a glass U tube 45 cm long mounted on wooden stand with scales fixed to each side of the stand.

This apparatus is used to measure surface tension by Capillary rise in a small bore. It comprises six glass capillary tubes 125 mm long, ends ground flat, of different bores, supported by a metal frame in a shallow metal trough.
