5 axes LHe Cryostat Manipulator (closed cycle, 20K)



The Manipulator with Helium Cryostat is a versatile, closed cycle system that has many applications in ultrahigh vacuum research. The manipulator can be configured with Z Slide, XY Stage or Differentially Pumped Rotary Feedthrough. The modular construction means that the specification can be upgraded or modified by the addition or replacement of well defined modules. The standard mounting flange is DN 100CF.


The Manipulators are used for positioning of sample holders and scientific tools with the ability to rapidly cool small samples (~2x2x0,3 mm). These manipulators, when combined with sample holders, allow precise placement and manipulation of samples in UHV environments. Samples can work in any orientation.

Additional information

The Manipulators are configured with a Sample Receiving Station that accepts mini ‘PTS’ sample holder. All of the manipulator axes can be motorised. The closed cycle Cryostat Head is produced by Advanced Research Systems, Inc. The system typically includes a compressor, high pressure hoses, expander, temperature controller, heater and sensor.
