Cryospot 4

The Cryospot 4 is our most versatile cryogenic system. It can be equipped with any GM cryocooler in the 0.1W - 1W capacity range, and has eight input/output ports. This system is ideal when vibrations from the GM cooler will not impact your experiment. Available with 12h, 24h, or 36+ hour sorption fridge add-on for experiments at 0.8K. This standard system can be configured to support up to 16 detector channels, and can be extended to 32 detector channels.
