1 COLLAPSING CANS With metal insert seal and screw cap to ensure a good seal - supplied but not fitted, otherwise the insert may be damaged during removal thus not sealing in the hot water vapour after heating. As the vapour cools the can collapses! Cat No. Description Price Per HPG-300-100 Collapsing Cans 3.04 ea. 2 MANOMETER Glass manometer with built-in stopcock mounted on backing plate. Scale 80-0-80 with 2mm subdivisions. Backplate dimensions: 400 x 80mm. Cat No. Description Price Per HPG-650-100 Manometer, Mounted 30.80 ea. 3 KINETIC THEORY MODEL For demonstration of the kinetic theory of gases explaining the molecular motion of gases. A pair of colour-coded 4mm socket terminals provided for electrical connection. Includes 3mm metal spheres and free-sliding cardboard discs for loading at the top. Cat No. Description Price Per HPG-550-100 Kinetic Theory Model 71.89 ea. 4 CARTESIAN DIVER Partially fill the diver with water, pop him inside a plastic drinks bottle full of water (not included) and screw down the cap. This simple submarine bobs just below the surface, but squeeze the bottle and he sinks to the bottom. It works due to changes in air pressure, and three ‘weights’ are provided so you can play at getting the diver to hook them from the bottom. Cat No. Description Price Per HPG-220-100 Cartesian Diver 4.08 ea. 5 HYDRAULIC PRESS Comprises a pair of graduated glass syringes of capacities 50 and 20cm 3 , both having finely ground pistons and providing a cross-sectional area ratio of 3:1 respectively. Both the syringes have loading platforms on their tops. A 3 way tap allows the syringes to 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. The thick walls of the syringes allow them to be capable of withstanding the pressures involved. Cat No. Description Price Per HPG-450-100 Hydraulic Press 118.81 ea.
