Model EMPX-H2 Cryogenic Probe Station

The Lake Shore EMPX-H2 probe station enhances standard probe station capabilities with the addition of a ±0.6 T horizontal field electromagnet. All standard C-V, I-V, microwave, and electro-optical probing, plus in-plane horizontal field electromagnetic measurements can be performed on this versatile station. Researchers can use it for testing magneto-transport parameters. The EMPX‑H2 is Lake Shore’s premier probe station for vector-dependent magneto-transport measurements.

To maximise magnetic field at the sample, the EMPX-H2 probes are configured at 30° angles for probing wafers up to 25 mm (1 in) in diameter. A 360° sample stage rotation option allows measurement of angular-dependent and anisotropic magneto-transport properties. The EMPX-H2 operates over a temperature range of 4.5 K to 400 K, with options to extend the base temperature to 3.2 K. The continuous refrigeration EMPX-H2 can be operated with liquid helium or liquid nitrogen for cooling.
