BOYLE'S LAW APPARATUS ADVANCED (0061)
Designed for Boyle's Law demonstration in wide pressure ranges to a group of students, results can be observed even from a distance. The apparatus comprises a thick walled, wide-bore glass tube mounted vertically in front of a scale graduated 0 to 65cm3, with closed end of the tube at the top and open bottom end secured tightly on the thick-walled metal tube with O-ring to get leak-proof joint. Other end of metal tube connected to a cylindrical oil chamber filled with colored oil and capable of withstanding high pressures. Zero of the scale corresponds to the inside of the closed [top] end of the tube with the scale reading directly indicating volume of the air enclosed in the tube. Oil chamber fitted with Bourdon gauge at the top. calibrated 0-3.4 x 10 Nm2 and has a valve on one side for connection to air compression pump. As the pressure in the oil chamber is increased, oil is forced into the glass tube compressing the air contained therein and the volume of the contained air and its actual (total) pressure is directly indicated. The glass , tube has thick walls of high strength having a very large safety overload margin. A transparent safety screen is mounted securely in frpnt of glass tube as an added safety measure. Supplied without pump and oil.

BOURDON GAUGE (0062)
For the measurement of actual gas pressure and not gauge pressure. Comprises of a circular gauge about 100mm diameter. The dial has dual scale reading 0 to 50 Lbs / in2 and 0 to 3. 5kg / cm2 pressure. and the case has a transparent perspex back to clearly observe the working of the gauge mechanism. A riffled tubule present at its one side provides gauge connection through rubber tubing. A thick black pointer needle against white dial provides easy reading of scale directly giving the actual pressure. Mounted on heavy cast-metal base for stability.

BOYLE'S LAW / CHARLE'S LAW APPARATUS (Combined) (0064)
Also called Jolly's Apparatus. It demonstrates the relationship between pressure and temperature of a given mass of gas at fixed volume, i.e .? Charle's Law. Comprising Jolly's Air bulb connected to a glass mercury reservoir through flexible rubber tubing. The complete apparatus mounted on a polished wooden stand with heavy cast metal base having leveling screws. A meter rule graduated 0-100cm x 1 mm. reading in both directions is fixed on the stand for reading the levels directly. Mercury reservoir tube mounted on vertical support rod with the help of sliding bracket that can be positioned anywhere along the length of the rod. Can also be used as Boyle's law apparatus by using a glass tube with one closed mounted on a slider that slides vertically in slot provided alongside meter rule. Complete with pressure rubber tubing and set of 2 glass tubes. Supplied without mercury.

FOOT PUMP (0067)
For use with Boyle's Law apparatus, or any other application needing manual compressed air source or blowing of air. A metal cylinder has an outlet tube with pressure gauge present at its one end and piston with foot?pedal attached at the other end. Pressing the pedal down and releasing it moves the piston in and out of the cylinder, pushing the air through the flexible hose pipe, which has a standard automobile tyre valve connector at its free end. A set of adaptor is included to facilitate the connection of flexible hose pipe to various inlets
