Closed-cycle Cryostat
The closed-cycle cryostat provided by Dexing is a variable-temperature cryogenic platform based on SHI 4K chiller in Japan, which is used for magnetic, optical and electrical measurements in low-temperature environments. Users can choose to match or special order, introduce optical window, special bench, special length, etc., combine with the user's experimental system, complete magneto-optic, photoelectric, optical reflection, light transmission, fluorescence and magnetoresistance experiments.
Main features: high cost-effective, compact structure, no consumption of refrigerants, strong expansibility.
