A typical system consists of:

  • OptistatCF-V helium cryostat including cooling unit and OptistatCF-V tail set
  • Sample holder
  • Up to five sets of windows. (four radial; one axial); each set includes two windows (radiation shield and outer case windows)
  • Cryogen transfer tube: LLT 700
  • Mercury iTC temperature controller
  • High vacuum pumping system
  • Helium dewar

Optional items:

  • Gas flow pump
  • Gas flow controller
  • Automated transfer tube allowing fully automated control across the entire temperature range
  • Wiring and electrical connections to the sample

Window options:

  • A wide range of window materials can be fitted to the OptistatCF-V to meet specific spectroscopy applications
  • Special windows with non-parallel faces and anti-reflection coatings are available
  • Additional or replacement window flanges available via the Oxford Instruments Direct - Cryospares® online catalogue

Pump options:

  • A simple oil-free vane pump GF4 is supplied for operation to 3.4 K
  • Lower temperatures to 2.3 K require an EPS40 single stage rotary pump

Transfer lines:

  • Oxford Instruments Low Loss Transfer tubes (LLT) use the cold gas exiting the cryostat to cool the shields surrounding the incoming liquid within the transfer tube. As a result, the consumption of our cryostats is the lowest on the market, dramatically reducing your running costs.

    We can also offer an extra flexible transfer tube for those with restricted space in their labs. Please note that as this does not use the gas cooled mechanism, helium consumption will be higher than for the LLT range. However it will be well suited to those who need a lightweight and more flexible transfer tube.

  • An auto needle valve can be fitted to the LLT which allows the temperature controller to optimise the helium flow rate
