Closed Cycle Cryostats

The majority of our vacuum shrouds attach to the cryostat via a double o-ring which allows for rotation of the sample with respect to the vacuum shroud. Most customers find this useful as it allows them to rotate the sample in a magnetic field or allow for glancing angles for optical experiments. Our systems can also interface with ISO flanges or CF flanges if desired.

These cryostats are sometimes referred to as ‘helium-free.’ A more accurate term would be ‘liquid helium free,’ since they do use helium gas, in a closed loop. This efficient recycling of the helium gas means that typically you will only need to add helium once every few years.
