Bell Jar

Bell Jars are made from:
– Stainless Steel 304 or 316L
– Pyrex
– Aluminum

Collar
A feedthrough collar with varying numbers of flanges may be inserted between the base plate and bell jar. The feedthrough collar can be used with a glass bell jar and L-gasket or our stainless steel bell jar with 7056 glass viewport. Like the collar, the bell jar is provided with a Viton O-ring and has a dovetail groove in its base.

Base Plates
Base plates come in a variety of sizes with smooth faced flanges to bolt directly to the vacuum pump. They may also be furnished with other types and sizes of flanges.
