Closed-End CF Glass Adapters

Closed Dome, Single-Flange Glass Adapters on CF Flanges

Glass-to-Metal Tube Adapters

The process used in joining borosilicate glasses 7740 Pyrex ® and 7052 glass to low-expansion NiFe alloys such as Kovar®, and/or non-magnetic alloys such as 304 stainless steel, is a highly specialized technology. Accu-Glass offers a wide selection of durable and reliable high and ultrahigh vacuum glass-to-metal tubular adapters. Our glass-to-metal adapters are available in rigid and flexible (with stainless steel bellows) configurations and fitted with industry standard ISO or CF vacuum flange mounts. These closed-end CF glass 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. UHV rated adapters are fitted with Conflat® compatible, metal seal CF flanges, while HV rated devices use standard, elastomer seal, quick-release ISO flanges.
