RGC Helium Recirculation
Quantum Design UK and Ireland offers the Lake Shore Cryotronics Recirculating Gas Coolers – a cryogen-free solution that allows you to use an LHe cryostat without the LHe. It’s ideal for low vibration, with excellent thermal performance.
The problem
You want the benefits of a LHe cryostat, but LHe is expensive and difficult to continuously source.
The solution
The RGC brings together the best of both worlds; the low temperatures, sample throughput, and low vibration of LHe cryostats, without the additional cost of LHe.
What is a recirculating gas cooler?
A recirculating gas cooler is a cryocooler-based system that continuously recirculates helium in a closed loop, enabling a continuous-flow LHe cryostat to operate cryogen-free.
How it works
The RGC runs helium in a closed loop, making a continuous flow cryostat cryogen-free. Helium gas is cooled and liquefied by the RGC’s cryocooler, and travels to the cryostat through a flexible vacuum-insulated transfer line. LHe cools the sample. The RGC captures the evaporated gas through the transfer line and reliquefies it, continuously recirculating the helium.
Ideal for low vibration
Commonly paired with a Lake Shore ST-500 cryostat, the combination is an ultra-stable cryogenic microscopy platform.
