1. Safety instructions
• Protect the surface of the vacuum experi-
ment plate from moisture, chemicals and
mechanical affects to guarantee that the
system remains vacuum-tight.
Defective vacuum bell jars could implode.
• Before conducting experiments check the
vacuum bell jar for any damage (entrapped
air does not endanger operating safety).
2. Description
Vacuum experiment plate and vacuum bell jar
are used to set up a vacuum chamber for ex-
periments in the coarse (low) and fine vacuum
range.
2.1 Vacuum Experiment Plate
The vacuum experiment plate comprises a me-
tal plate with rubber sealing disc mounted on a
tripod and two cock valves used for hose con-
nection on the pump side as well as for ventila-
tion. A center bore hole with M12 thread is used
to secure experiment equipment. A vacuum-tight
power feed with 4-mm safety sockets and two
cables with 4-mm safety plugs are available for
the power supply.
