CF-UHV Vacuum Fittings
In the ultra high vacuum range (UHV) with pressures <10-8 mbar cleanliness of the chamber and the flange components is critical. The gas desorption rate is an important factor for achieving UHV conditions. The manufacturing technique, surface treatment and cleaning processes guarantees a low desorption rate. To reach the UHV range as quickly as possible, baking the UHV system at 300 °C with the vacuum pumps running is recommended. At these temperatures elastomer gaskets are suitable for test purposes only. All flange connections are sealed with OFHC copper gaskets (oxygen-free high conductivity copper). CF-flanges are equivalent to Conflat®.
