CRX-4K
High performance closed cycle refrigerator-based probe station
• Cryogen-free operation
• Allows unsupervised cool down
• Low temperature operation
• Minimizes sample condensation during cooldown
• Customizable to accommodate a 102 mm
(4 in) wafer
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 lowtemperature
cryogen-free performance, with configurations
enabling sample temperatures as low as 4.5 K. Multiple
temperature sensors throughout the station ensure accurate,
repeated measurements.
