ULVAC offers ultra-high vacuum flanges (fixed, rotatable, conversion), ultra-high vacuum zero length viewing windows, current feedthroughs, etc.
The UFC Series are knife-edge metal-seal bakeable flanges for ultra-high vacuums.
Ultra-high vacuum conversion flanges are used to connect UFC flanges of different sizes. (UFC flanges are knife-edge metal-seal bakeable flanges for ultra-high vacuums.)
The TVU-FV Series are viewing windows with a wide field of view. They enable observations of ultra-high vacuums in vacuum containers, from the atmosphere side. Their connecting flanges are knife-edge metal-seal bakeable types for vacuum systems.
The TDU Series are rotary feedthroughs enabling objects in vacuum chambers at ultra-high vacuum pressure to be rotated manually from the vacuum system's atmosphere side. When the handle on the atmosphere side is turned, the rotation is conveyed through a bellows to rotate the shaft on the vacuum side.
The TSU Series are linear feedthroughs enabling objects in vacuum chambers at ultra-high vacuum pressure to be moved linearly from the vacuum system's atmosphere side. When the handle on the atmosphere side is turned, the shaft on the vacuum side moves in a linear direction.
The CMS Series are electrical feedthroughs for passing current and applying voltage to vacuum chambers with pressures ranging from atmospheric pressure to ultra-high vacuums.
