U45052 Vacuum set for students

8/03 ALF

Equipment set for practical experiments introducing the

basics of vacuum physics. Subjects that may be studied

experimentally may include, for example:

• Determining the mass of air evacuated and its density.

• Effect of air pressure on a partially inflated balloon

and a miniature bellows.

• Lowering of boiling point of liquids by reduced air

pressure.

1. Safety instructions

• When attaching hoses do not use excessive force. Do

not exert more than the pressure of your fingertips

on the hose connectors when joining them together.

• To clean, use only warm water with a small amount

of washing-up liquid. Never use solvents.

2. Description, technical data

A complete set of equipment consisting of an experi-

ment plate incorporating a rubber ring and a bell jar that

can be joined together with a recipient to enclose a coarse

vacuum. The bell jar is equipped with a hose connection

for attaching a plastic hose with a built-in valve. Evacua-

tion is achieved using a simple hand pump. Beakers,

bellows and balloons are provided for the experiments.

All components are made of transparent plastic.

Experiment plate: 70 mm Ø approx.

Bell jar: 90 mm high approx.
