規格說明 / Specification:


Helium cryostat 4K sample in exchange gas OptistatCF2 continuous flow helium cryostat, sample in exchange gas ideal for experiments requiring high sample throughput and low conductivity samples


  • Wide temperature range

  • Quick sample change in less than 5 minutes via top-loading sample probe

  • Superb optical access for measurements requiring light collection

  • Optimised clear beam throughput (15 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 0.55 L/hr at 4.2 K using a Low Loss Transfer tube

  • Versatile: wide range of sample holders/rods including liquid cuvette for liquid samples and precise height adjust/rotate sample rod

  • Compact size allowing easy integration into commercial spectrometers

  • Electrical measurements via 10-pin electrical feed wire to heat exchanger and/or wired on coax connectors

  • 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)

  • Two models to choose from: static or dynamic exchange gas
