PYREX®-to-Soft Glass Adaptors

PYREX® to soft glass is used when a reliable vacuum seal is required between a borosilicate glass and a lime soda glass. A short stainless steel sleeve between the two glasses allows this adaptation.  This is also a nonmagnetic assembly.

  • Other non-standard sizes available

Larson Electronic Glass offers PYREX®-to-Soft Glass Seals (with a stainless steel transition section) available in 5 standard sizes from 9mm through 19mm and are also offered in other non-standard sizes. Dimensions are in mm unless otherwise noted.
