This ³He refrigerator is based on advanced sorption pump technology combined with the specially engineered 1 K condenser and ³He pot. 

  • Quick sample change
  • Easy to use
  • Compact design
  • Can be combined with a magnetic sample environment
  • For magnetic fields below 6 T, a small magnet can be mounted on to the IVC tube and provides magnet operation in a transport dewar
  • For magnetic fields over 6 T, the HelioxVL is combined with magnetic environments with our Integra product range, providing magnetic fields up to 21 T
  • HelioxVLis compatible with IntegraAC, the recondensing liquid helium cryostat. IntegraAC has been developed to significantly reduce the consumption of liquid helium by recondensing helium gas evaporated within the system, which would otherwise be vented from the cryostat. This decreases the frequency of helium refills. Cryogenic systems can be kept cold continuously, even when in stand-by mode, leading to greater freedom to schedule experimental time

A complete system consists of:

  • An insert including the self-contained ³He dump and cryogenic pump
  • An external small pump for the 1 K condensing stage
  • The controlling electronics and software
  • The diagnostic wiring

Flexibilty: Heliox insert systems suit all experiments at temperatures around 300 mK with single shot ³He refrigerators

Low maintenance: the Heliox has an in-built cryopump 

Low vibration: the combination of cryogenic pumping and a coil condenser at 1 K provides an excellent environment for vibration-sensitive measurements 

Base temperature: ≤ 245 mK for ≥ 90 hrs with no applied heat load

Cooling power: 40 μW at ≤ 290 mK, with a hold time > 10 hrs 

Temperature range: Base temperature to 300 K 

Temperature stability: ±3 mK for T ≤ 1.2 K and ± 0.1 K for T > 1.2 K
