Quantachrome Instruments Low-Cost Cryogenic Temperature Controller for Gas Sorption Analyzers CryoSync™ Cryocooler

This amazingly powerful and affordable cryocooling accessory allows users of Autosorb iQ analyzers and other gas sorption instruments to smoothly synchronize the generation of precise sorption analyses at liquid argon temperature (87 K), while using less expensive liquid nitrogen (77 K) as the cryogen, with the newest IUPAC recommendations (Thommes et al., Pure Appl. Chem. 87(9-10), 1051-1069 (2015)). Features: • The CryoSync™ Cryocooler uses liquid nitrogen (77 K) to generate user-programmable liquid argon temperature (87 K) with excellent precision. • A standard cell with the sample to be analyzed is placed on a thermostatic block whose temperature is accurately controlled by warming a heat sink immersed in liquid nitrogen. • The CryoSync™ Cryocooler is capable of maintaining excellent temperature stability in the thermostatic block, with a standard deviation better than ± 0.005 K for a minimum of 50 hours. • Although the CryoSync™ Cryocooler can work without a PC, it is supplied with Windows-compatible software that allows temperature monitoring and recording in real time. • The CryoSync™ Cryocooler, developed by Quantachrome Instruments (patent pending), provides a very cost-effective and convenient way to meet the latest IUPAC recommendations for argon-87K-based micropore analyses on any gas sorption instrument that accepts an external temperature control option.
