Two near-hemispherical rubber cups, when held together face to face and squeezed to force out the entrapped air, it becomes surprisingly difficult to pull them apart. Each hemispherical cup is about 75mm in diameter and has two finger handles for holding them and pulling them apart. Also has two release posts for releasing the inside vacuum.

To demonstrate the effect of Bernoulli’s theorem by studying variation in the pressure and speed of flow of an incompressible fluid through a tube with respect to the tube bore or cross-section. Comprises a Bernoulli’s tube, with central constricted portion, a constant bore gradient tube, 6 lengths glass tubing, 2 swan necked outlets tubes and 8 small pieces of rubber connecting tubing for joining various glass tubings as and when needed. The two flow tubes, each 500 x 13mm (L x OD) have three sealed-in short side tubes of length 25mm each with interspacing of about 150mm for connection to glass tubing lengths for use as manometers. The middle short side tube in Bernoulli’s tube stem out from the central constricted portion for studying the effect of constriction.

For the measurement of actual total gaseous pressure. A circular gauge about 100 mm diameter, has a scale reading 0 to 3.4 x 105 Pa pressure. The case has a transparent back to clearly observe the working of the gauge mechanism. A riffled tubule provided for inlet tubing connector. A thick black pointer needle against white dial facilitates easy reading of the scale directly giving the actual pressure.

Designed for Boyle’s Law demonstration in wide pressure ranges to a group of students with adequate safety features and results can be observed even from a distance. A thick walled, wide bore glass tube with closed end at the top is mounted vertically in front of a scale graduated 0-65cm square, with its lower open end mounted securely on a thick walled metal tube, with the later connected to an oil chamber. The oil chamber has a bourdon gauge calibrated 0-3.4 x 105 Nm square at the top and has a valve on one side for air pump connection. Zero at the top of the scale facilitates reading the volume of air enclosed directly from the oil level in tube. A transparent safety screen is mounted as an added safety measure. Supplied without pump and oil.

Demonstrates the relationship between pressure and volume of a given mass of gas at a fixed temperature, i.e., Boyle’s Law. Consists of two glass tubes and one having both ends open and the other having its upper end closed. Both the tubes are mounted on vertical support rods with the help of sliding brackets that can be positioned anywhere along the length of the rod and are connected to each other through a flexible pressure rubber tubing. A meter rule graduated 0- 100cm x 1mm, reading in both directions, is located between the two support-rods on a wooden back plate and facilitates liquid level reading in both the tubes. Complete apparatus mounted on a stable cast-metal base with leveling screws. Requires mercury for use, not included (available optionally).
