The vacuum interface devices are mounted on UHV vacuum flanges, based on the established Conflat®; design, in which a precision OFHC copper gasket is captured between two knife edge sealing surfaces. They are also available mounted on ISO and other 'O' ring sealed flanges with an equivalent tubulation to the conflat mounted detectors.
