Model CRX-4K Cryogen-Free Probe Station
Lake Shore Cryotronics
Designed for versatility and high performance, the CRX-4K is our premium cryogen-free closed cycle refrigerant probe station. This system is the solution for those looking for the convenience of cryogen-free operation and the exceptional measurement performance of a Lake Shore product. Using a self-contained closed cycle refrigerator (CCR), the station cools down to cryogenic temperatures unassisted, eliminating the need for monitoring by the researcher. Various options and configurations on the CRX-4K enable the researcher to conduct exacting, challenging test measurements.
The CRX-4K provides Lake Shore's best low-temperature cryogen-free performance, with configurations enabling sample temperatures as low as 4.5 K. Multiple temperature sensors throughout the station ensure accurate, repeated measurements. The 2-stage CCR allows the sample to be maintained at elevated temperature during cooldown, reducing the potential for condensation, a critical requirement for measuring organic materials. The CRX-4K is designed to accommodate wafers as large as 102 mm (4 in) in diameter, with 51 mm (2 in) diameter probable regions.
