Our Vacuum bell jars are available in many sizes, including the popular and enduring 12" x 14" used on laboratory coating units.
Unlike some suppliers our Bell Jars and Cylinders are measured on the internal diameter (ID) as we are aware that some supplier's bell jars are a tight, if not impossible fit over existing electrode configurations.
All our Vacuum Bell Jars and Cylinders are manufactured from Borosilicate glass, the edges are fire polished and then ground. After manufacture all are fully annealed to give maximum strength and minimum stress within the material.
