Glass to Metal Tube Adapters for Ultrahigh (UHV) High In-Vacuum (HV) applications
The process used to join 7052 borosilicate glass or 7740 Pyrex® to low-expansion NiFe alloys such as Kovar®, and/or non-magnetic 304 stainless steel, is a highly specialized technology.
Accu-Glass offers a wide selection of durable and reliable high vacuum (HV) and ultrahigh vacuum (UHV) glass-to-metal tube adapters.
Our glass-to-metal tube adapters are available in rigid and flexible (with stainless steel bellows) configurations and fitted with industry standard ISO or CF vacuum flange mounts. These adapters are designed for simple and reliable installation of 'tubular' laboratory glass instruments onto 'metallic' high and ultrahigh vacuum systems and/or the attachment of standard metal vacuum components onto glass laboratory apparatus. Single and double-ended flanged configurations with open, closed, rigid and flexible interfaces are available.
Single ended devices have either open or closed (domed) glass tube terminations on the end opposite the vacuum flange mount. In-Vacuum rated adapters are fitted with Conflat® compatible, metal seal CF flanges, while HV rated devices use standard, elastomer seal, quick-release ISO NW KF and LF flanges.
