Ultrastat

A small (1 Kg) and highly efficient platform designed for applications requiring UHV environments. The system provides clean sample environments for applications such as Nanotechnology and Nanoscience.

The UHV Ultrastat is cooled by a continuous flow of liquid helium using standard ancillary items. It can operate in any orientation. Because of its small size it takes only 1 litre of liquid helium to cool the Ultrastat from room temperature to base temperature.

The UHV Ultrastat is constructed entirely from UHV compatible materials and can be baked to 500K.

Samples can be mounted directly on to the heat exchanger and temperature controlled between 3.8 – 500K using a heater and rhodium-iron sensor mounted at the cold tip. Alternatively the cryostat may be used as a cold finger with a copper braid used to connect the sample to the face of the cold tip. Standard mounting is via a DN40CF (70mm outer diameter) conflat flange.
