Linear Transfers

Designed to transport sample holders/samples between chambers under UHV conditions.



Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.


They are commonly used to transfer samples from load lock chambers to UHV system main chambers. The linear transfers are pumped by the research platform pumping system or else with a dedicated pump set. The entire movement range of the transfer mechanism is via rotary motion feedthrough. The range of the transfer movement is from 450 to 1600 mm.

There are two types of linear transfers available:

  • 1 axis – with forward movement only,
  • 2 axes – with forward movement and continuous rotation around the movement axis.

Two-sided solution

Two sided linear transfer allows for transferring through linear transfer chamber in both directions. Chamber can be equipped with additional ports for connecting e.g. pump.

The range of the transfer movement is from 500 to 2000 mm.
