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).

are used to set up a vacuum chamber for ex-
periments in the coarse (low) and fine vacuum
