Probe stations are versatile and flexible Typical applications include sampling I-V and C-V curves over a wide range of temperatures, measuring microwave and electro-optical
responses, characterizing magneto-transport properties in variable magnetic fields, Hall effect measurements to understand carrier mobility, and a variety of other material studies.
Lake Shore Cryotronics offers a variety of cryogenic probe stations providing the environment of 1.6 K to 675 K temperature, -2.5 T to 2.5 T magnetic field with the stages for up to 2” wafers and 4” wafers optionally.
CRX-4K Cryogen Free Closed Cycle Probe Station
Designed for versatility and high performance, the CRX-4K is our premium cryogen-free closed cycle refrigerant probe station. Using a self-contained closed cycle refrigerator (CCR), the station cools down to cryogenic temperatures unassisted, eliminating the need for monitoring by the researcher.
The CRX 4K provides Lake Shore’s best low-temperature cryogen-free performance, with configurations enabling sample temperatures as low as 4.5 K.
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 4” in diameter, with 2” diameter probable regions.
CRX-6.5K Cryogen Free Closed Cycle Probe Station
The CRX-6.5K provides a low-cost, general-purpose solution for those looking for the convenience of cryogen-free operation and the dependable 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. 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-6.5K operates over a temperature range of 8 K to 350 K with the option to extend to a higher range of 20 K to 675 K. This model accommodates full and partial wafers up to 2” in diameter.
CRX-VF Cryogenic Probe Station
The CRX-VF is a cryogen-free, closed-cycle refrigerator probe station enhanced with a ±2.5 T vertical field superconducting magnet. It performs C-V, I-V, microwave, and electro-optical probing, plus out-of-plane vertical field superconducting magnetic measurements. Researchers can use the CRX-VF for performing Hall effect measurements and testing magneto-transport parameters. It is designed to enable true 90° wafer probing on wafers up to 2” in diameter.
The sample is maintained at elevated temperature during cooldown, reducing the potential for condensation, a critical requirement for measuring organic materials. Using a self-contained closed-cycle refrigerator (CCR) it operates over a standard range of 10 K to 500 K.
