A bell jar vacuum chamber is a piece of laboratory
equipment used to contain vacuum. It is similar
in shape to a bell, and can be manufactured
from a variety of materials (ranging from
glass to different types of metals). Bell
jars are generally used for classroom demonstrations
or by hobbyists, when only a relatively low-quality
vacuum is required. Cutting-edge research
that needs an ultra-high vacuum requires
a more sophisticated form of vacuum chamber.
However, several tests may be completed in
a chamber with an effective pump and low
leak rate.
The HTC vacuum Bell Jars chambers are designed
to be used with flat Baseplates, Base Wells
and Feedthrough Collars, all the above pieces
are made of stainless steel. The number and
size of ports, type of flanges, view port,
O-ring material and surface finish option
are available upon request.
