These cryostats cool the sample in exchange gas using a closed-cycle refrigerator, so no liquid cryogen is needed. Samples may be solid, liquid or powder, conductive or non-conductive, and are changed in under 10 minutes. A wide choice of feedthrough and window options is offered.

The SHI-950-LT cryostats use a closed-cycle refrigerator to cool samples in exchange gas to 1.5 K without liquid cryogens. An optional helium-3 insert takes the base temperature to 300 mK, and the upper limit is 800 K. Optical and non-optical versions are available.
These cold traps use a mechanical closed-cycle cooler to adsorb noble gases, including helium, neon, argon, krypton and xenon. The cold surface is held below 9 K so gas is captured from a vacuum line without liquid cryogens. Three models cover different upper temperature limits.
The CCS-XG closed-cycle cryostats reach below 4 K with sample vibration held to 40 nm, avoiding the movement usually associated with cryogen-free cooling. The CCS-XG-UHV version is built for ultra-high vacuum work and can be baked at 200 °C with the cold head removed.
