UHV Accessory Products For All Applications

Fixed blank Conflat flange (CF) are available in the full range of sizes. These are used to blank off unused chamber ports for leak-tight assembly, also allowing End User machining for non standard tube sizes or components.

Rotatable blank Conflat flange (CF) consists of two parts, the inner knife edge detail and the outer bolt hole retaining ring which rotates around the inner part. This allows the boltholes to align to mating flanges in any orientation. These are used to blank off unused chamber ports for leak-tight assembly, also allowing End User machining for non standard tube sizes or components.

Zero Length Adaptor conflat Flange (CF) are used to adapt from one flange size to another. The larger flange OD has through bolt holes enabling ordinary nut and bolt to be used. The smaller flange OD has metric tapped holes. This connects different sizes of flanges where there is limited space and does not increase the chamber volume.

Four way cross with flanges equally spaced at 90° to each other. On each axis, one of the flanges is fixed and the other is rotatable. The fixed flange comes in two versions of bolt hole orientation, inline or straddled configuration, enabling the connection in any orientation of the vacuum equipment.

Super clean ultra high quality oxygen free Silver plated gasket. These are rumbled to remove all the burrs, etched to remove surface skin prior to silver plating, UHV cleaned and individually packed. Completely free from any nickel flash base coat. Recommended for use in HV & UHV systems where the vacuum environment could oxidise a plain copper gasket.

Super clean ultra high quality oxygen free annealed copper gaskets for lower tightening torque to make a UHV leak tight seal. These are rumbled to remove all the burrs, UHV cleaned and individually packed. Recommended for use where you are using zero length viewports and fragile ceramic feedthroughs.

High quality oxygen-free copper gaskets for university and commercial use. These are rumbled to remove all the burrs, UHV cleaned and individually packed. Designed for UHV applications where high usage or bulk purchase pricing is required.

Viton® gaskets are used in HV applications with low bakeout temperatures (

HD range of fast entry lock doors can be used to load items into a prep chamber. The door is sealed by a reusable Viton® O-ring. This is an ideal solution for keeping the main system under UHV conditions via a gate valve between the load lock and system.

A zero length viewport has a thickness no larger than that of its mounting flange. This makes it easier to protect from accidental damage. It provides the best angle of view as there are no tubulation walls to restrict observation. Kodial viewports are offered in CF flange styles. The viewports comprise borosilicate glass optic which is sealed to a Kovar weld ring using an induction heater process. The optic assemblies are helium leak tested and cleaned for ultra high vacuum (UHV) conditions.
