CRX-4K

CRX-4K probe station

Designed for versatility and high performance, the Lake Shore Model 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 will cool 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. More information about the CRX-4K...
