holding vacuum pressures. All HyVac bell jars are made from ultra high purity,
extra dense glass. Standard option items are a precision ground flange bottom and
/ or a knob on top
for easier manual manipulation. The jars are also available with a plain
bottom and regular round or dome top. We have some sizes that
accomodate a rubber stopper in the top of the dome radius.

available, as are some used chambers.
