CPX

CPX probe station

With a modular design to meet the needs of a breadth of experiments, the Model CPX is Lake Shore’s most versatile, high performance cryogenic probe station. Various options and configurations on the CPX enable the researcher to conduct exacting, challenging test measurements. The CPX has multiple radiation shields to provide Lake Shore’s best low temperature performance with configurations enabling sample temperatures as low as 1.6 K. Multiple temperature sensors throughout the station ensure accurate, repeated measurements.

Due to the split flow design, the sample stays warm while the shields cool, which, along with the high vacuum option, minimizes sample condensation during cool-down—a key requirement for measuring hydrophilic organic materials. Ideal applications include research in organics and microwave measurements. Vacuum load-locks are configurable for conducting high-throughput measurements. In addition, the CPX can be configured to enable controlled sample transport under vacuum to the chamber. The CPX accommodates 51 mm (2 in) diameter wafers (up to 102 mm [4 in] optional). The system operates with either liquid helium or liquid nitrogen. More information about the CPX...
