What your adsorption lab actually checks
Any temperature, no refills
35–473 K under program with ±0.001 K stability and no liquid-nitrogen top-ups — variable-temperature adsorption, isosteric heat and gas-storage isotherms that a fixed 77 K bath can't reach.
A materials engineer on the line
Compatibility, integration and isosteric-heat method support from engineers who run adsorption analysis in-house at Additive Plus. Sub-4h reply, NDA standard.
BELCRYO X is a closed-cycle cryogenic unit for the BELSORP series — programmable temperature control from 35 to 473 K without liquid-nitrogen top-ups, with ±0.001 K stability for variable-temperature adsorption and gas-storage studies.
What Is the BELCRYO X: LN₂-Free Cryogenic Control
The BELCRYO X is a companion unit that replaces the liquid-nitrogen Dewar on a BELSORP analyzer with a helium closed-cycle refrigerator. It holds any set temperature from 35 to 473 K, so adsorption isotherms are no longer fixed at 77 K and are never interrupted by a Dewar refill. See full specifications below.



Why adsorption labs add the BELCRYO X
Temperature freedom and stability without the liquid-nitrogen routine.
No liquid-nitrogen top-ups
A helium closed-cycle refrigerator holds the analysis temperature — no Dewar refills, no overnight level drift, no time limit on long isotherms.
Wide temperature window
35 to 473 K under program, so you run adsorption well beyond nitrogen’s fixed 77 K — hydrogen and methane storage, CO₂ separation, isosteric heat.
Ultra-stable
Temperature stability of ±0.001 to ±0.01 K keeps isotherms reproducible where a liquid-nitrogen bath drifts with level and time.
Seamless integration
Works with BELSORP MAX X, HP/HT, MAX G and MINI X through one BELControl workflow — up to three samples, pretreatment to measurement automatic.
