Differentially Pumped Rotary Feedthroughs

Rotary Feedthrough Platforms

Rotary platforms provide a means of translation into the vacuum vessel without compromising on vacuum integrity. Differentially pumped rotary feedthroughs (DPRF) are of annular construction to enable a probe or similar device to be inserted into a UHV environment and rotated. The RP100 with 100mm clear bore is designed primarily for use in Cryostat applications, as the large bore size can be fitted to the Omniax Widebore.

25mm Single Stage

Differentially Pumped Rotary Feedthrough
The DPRF25 is a single stage differentially pumped rotary feedthrough which comes in a variety of actuations with encoded stepper motor options available. The 25mm clear bore is our smallest design and can be fitted onto the Miniax or HPT manipulators.

55mm Dual Stage

Differentially Pumped Rotary Feedthrough
The DPRF55 is a dual stage differentially pumped rotary feedthrough which comes in a variety of actuations with encoded stepper motor options available. The 55mm clear bore can be fitted onto the larger sample manipulators such as the Omniax.

100mm Dual Stage

Differentially Pumped Rotary Feedthrough
The RP100 Rotary Platform is a dual stage differentially pumped rotary feedthrough with a low profile design. The RP100 was primarily designed for use with the Omniax Widebore Manipulator to provide 100mm clear bore into the vacuum vessel.
