Property of Matter Fluids

Catalogue No: 1020680_1

Working model made of borosilicate glass. Demonstrates the working principle of the force pump, concept of double valve action of the pump and its ability to eject water at high pressure. Comprises a glass cylinder with a non-return float valve at its lower end, which also has an outlet that in turn communicates to the lower end of a secondary cylinder also equipped with a non-return float valve. The outlet tube from a secondary cylinder is drawn out into a jet.

Demonstrates that the objects fall at the same rate of acceleration in vacuum under the effect of gravity irrespective of their relativ weights and sizes. Consists of a thick-walled glass tube fitted with rubber bungs at each end to seal the tube. One of the rubber bungs has a glass tube of about 8mm diameter fixed through hole in it that has rubber tubingwith clip for connecting it to vacuum pump.

Harbottle helps students understand the concept of fluid pressure and pressure reduction. It is a spherical glass container with a balloon stretched over its opening and a hole at the flattened base which is fitted with a rubber stopper. Students will be amazed to observe that the balloon remains inflated inside the bottle even though it is not tied off or sealed.

Simple construction permits the use of water or even air for demonstration of the concepts. Comprises a pair of graduated glass syringes of capacities 50cm square and 10cm square, both having fine ground pistons and provide a cross-sectional area ratio of about 3:1 respectively. Both the syringes mounted on a stable, non-skid sheet metal base with loading platform at their top and their nozzles linked to each other through a 3-position valve, by means of which they may be opened to the atmosphere, isolated or interconnected as desired. Both the pistons provided with limit-stop to prevent their complete ejection from the barrels. Thick wall of syringes makes it capable of withstanding pressures involved. The graduated syringe barrels also permit simple Boyle’s Law experiments to be performed.
