Differentially-pumped doors

These doors feature differentially-pumped seals for true-UHV (10-10 to 10-11 torr) operation. Unlike regular Quick Access doors, which are not truly UHV compatible, these allow easy access directly to the UHV environment. A variety of fitting sizes and styles, including mini-CF, VCR and KF / ISO flanges, on the pump-out line are available with any door. All models are bakeable to 150C. Although shown with a solid door in the photo, integral windows and tapped CF flanges are also available. Please consult the factory for pricing on special features and for delivery.
