RGC Series Helium Recirculating Gas Coolers
Lake Shore Cryotronics environment by Janis
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.
Cryogen-free: run an LHe cryostat without the LHe
Lake Shore SuperTran ST-500 Series continuous flow cryostats are specially designed for use in microscopy, imaging, and high spatial resolution photoluminescence. Combining the low thermal-expansion support structure and internal vibration isolation results in nanometer-scale vibration and drift levels. The cryostat geometry offers a short working distance for use with high magnification optics and permits mounting on common microscope stages and translators.
How does a recirculating gas cooler work?
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.
RGC Series recirculating gas cooler compatibility
The RGC is compatible with Lake Shore ST and STVP cryostats and can be used with some LHe cryostats from other vendors as well.
