Glass Adapters

Glass adapters

MDC glass to metal adapters provide a means of attaching glass components to a metal vacuum system and or metal hardware to a glass system. These glass adapters are produced with the latest in glass-to-metal seal technology and are available in either Pyrex® code 7740 or Borosilicate code 7052 glass. Five glass seal geometries are offered, these include flange to glass with open end, flange to flange with glass transition, flange to glass with sealed end, flange to glass with open end and flexible bellows transition and glass to glass with flexible bellows transition. Most are offered on 1-1/3 to 8 inch Del- Seal™ CF flanges with glass tube from 1/8 to 6 inch diameters. All overall lengths and glass lengths are nominal ±1/8". Products fitted with Kwik-Flange™ ISO KF flanges are available for tube diameters of 3/4, 1, 1-1/2 and 2 inches.

  • Single ended glass adapters
  • Double ended glass adapters
  • Sealed end glass adapters
  • Flexible glass adapters

The flange to glass with open end versions are designed for installation to a flanged system on one end and to either a quick disconnect elastomer sealed compression fitting or for fusing directly to a glass tube, apparatus or system. The flange to flange glass transition versions allow mounting between two flanged systems. They can also be used as low voltage electrical breaks on vacuum tube lines. Flange to glass adapters with a sealed glass end can be mounted to a flanged system and provide a bell jar like glass enclosure that is ideally suited for experiments requiring the transparency of glass. Flexible glass adapters are fitted with formed bellows and are specifically designed for joining metal flanged systems or glass tubed systems with misaligned components.
