VSV – Glass to below and glass adaptator

VSV 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 two glass components. 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) at both ends
  • 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

They are built on request either using a CTVM standard design or to customer’s own specification
