VSE – Glass to metal below & tube adaptor

VSE glass to metal tubular seals from CTVM are designed for vacuum and high-vacuum applications. They are used to make a leak-tight connection between a glass component and a metal accessory such as a flange or a fitting on a vacuum chamber. The bellow is used to offset a misalignment between the joined components, or break a sample tube filled with gas that has been inserted in the bellow before welding the accessories.

  • Borosilicate glass (PYREX®, boro 3.3)
  • 316 L stainless steel bellow
  • Kovar flanges
  • Bakeable at 400°c
  • Withstand thermal cycles and cryogenic temperatures
  • Leak tightness guaranteed to 1.10-9 mbar/l/sec minimum

VSE adaptors can be mounted onto CF or KF type flange using TIG welding or any other kind of setting used in the vacuum industry. They are built on request either using a CTVM standard design or to customer’s own specification
