Optistat ACV

Optistat ACV is a closed cycle, sample in vacuum cryogen free 4 K cryostat, no liquid helium required and easy to use. The cryostat is capable of achieving sample temperatures as low as 2.8 K without the need for liquid helium.  This brings significant benefits in terms of running cost and ease of use.

Key specifications for the cryogen free Optistat ACV

  • Low running costs
  • Wide temperature range 2.8 K - 325 K
  • Two models to choose from depending on your cooling power requirements
  • Easy sample change
  • Low vibration using a Pulse Tube Refrigerator (PTR).  Typical displacement amplitudes on the second stage heat exchanger in the radial and axial directions are typically 7 and 12 micrometers respectively
  • Large sample space, with a sample in vacuum environment, enabling studies of samples with a wide range of size and geometry
  • Optimised clear beam throughput (12.7 mm diameter aperture) allows a large illumination area for measurements involving the detection of low intensity light
  • Electrical measurements via 10-pin electrical feed wire to heat exchanger
