Hand vacuum pump HG0078
A hand pump equipped with two nozzles. One of them is used to pump out the air to create a vacuum, while the other nozzle generates overpressure, which will allow air to be pumped into, for example, a balloon. Connection with HG0077 Vacuum bell jar. • the inner diam. of the cylinder 2,25 cm; • length: 20 cm, nozzles: outer diam.: 0,9 cm; • hand grip: diam.: 2,8 cm, length: 10 cm; • material: steel, plastic, wood; • max. pressure: ≤ 6,7 × 103 Pa (500 mmHg), min. pressure: 2,9 × 105 Pa (3 kgf /cm2); • hose: 30 cm long
Vacuum bell jar HG0077
A vacuum bell jar for experiments in low pressure conditions; made of transparent plastic cloche and a base with a rubber sealing ring. It has an electric bell and
a hand pump. • base 19 x 25 cm; • cloche D 15 cm; • material: plastic; • age: 14+
Boyle’a-Mariotte’s law demonstration model HG0096 The device demonstrates Boyle’s law i.e. it shows a relationship between the pressure and volume of air at a constant temperature. The user can experiment with the elasticity of a measured amount of gas. Turning the handle compresses the air. The volume, temperature and pressure can be read from the display screen on the scales. • box dim 24 x 19 x 15 cm
Pascal’s pressure sphere demonstration model HG0099
Archimedes’ Law. Demonstration set QH003
A device to present Pascal’s law in action. It is made of a steel sphere connected to a tubular manual pump. The sphere is pierced with small holes. After filling it with water and pushing the piston the
The set for demonstrating Archimedes’ law, the basic law of hydro - and aerostatics, which determines the buoyancy force. The teaching aid makes it possible to explain the principle of Archimedes’ law for bodies immersed in water. The kit includes: • main container with drainage tube - overflow container; • graduated gravity container; • graduated beaker with measuring cup; • 10 weights; • weight spring; • dimensions 17,5 x 4 x 7 cm; • age: 6+
water squirts out in even jets. • L 35 - 53 cm, sphere D 8 cm, sphere V 0,2 l; • 9-10 holes
Newton’s tube HG0125
An apparatus for demonstrating how the motion of objects follows Newton’s second law of motion. • size: 5,8 x 95 cm; • the tube contains a magnet, metal coin and a feather
