We, Merrow Scientific, are now supplying the BELCryo system in the UK from our Japanese partner BEL. The BELCryo allows users to carry out research into adsorption at extremely low temperatures. 
The BELCryo has a wide temperature range, allowing measurements to
be carried out between 50K and 473K (so about -220degC to 200degC) and
with a tight control on the temperature (accuracy of about +/-2mk at
77K)
The BELCryo system can be used in conjunction with a Belsorp Mini II, Max or HP
to allow measurements of gas sorption to be carried out at any
temperature between 50K and 473K, so such research applications as gas
storage into MOF materials.
Coolant (such as liquid nitrogen) isn’t required so there are no
issues regarding monitoring of coolant levels and related time
restrictions.
