規格說明 / Specification:


Our helium cryostat 4 K sample in vacuum cryostat, with the lowest helium consumption on the market, is well suited for experiments requiring a large sample space and minimum number of windows in the optical beam path (reducing reflective losses).

It is also a very versatile instrument as its tail is interchangeable between MicrostatHe2 and MicrostatHe2 Rectangular tail, ideal for microscopy and Magneto-optical Kerr effect experiments.

  • Wide temperature range: from 3.2 K to 500 K

  • Large sample space enabling studies of sample with a wide range of size and geometry

  • Superb optical access (f/0.9) for measurements requiring light collection

  • Optimised clear beam throughput (23 mm diameter aperture) allows a large illumination area for measurements involving the detection of low intensity light

  • The most economical use of cryogens on the market: less than 0.45 L/h at 4.2 K using a Low Loss Transfer tube

  • No cold windows enabling the use of any window material above 300 K

  • Demountable radiation shield windows to maximise transmission intensity

  • Compact size allowing easy integration into commercial spectrometers

  • Electrical measurements via 10-pin electrical feed wire to heat exchanger

  • Can be operated in pull mode (using a gas flow pump to pull the helium from a storage dewar to the sample space) or push mode (by pressurising the storage dewar).
