I. Product Overview
ABN's PS Probe Station is an economical, multi-functional benchtop cryogenic probe station, serving as an ideal option for laboratories with limited budgets or those newly engaged in material testing. The system features an extremely short lead time, and cryogenic experiments can be initiated merely with a vacuum pump and refrigerant. Pre-configured for high-sensitivity, high-impedance DC measurements, the PS probe station supports a wide range of applications. It adopts a four-arm triaxial TTPX probe station setup for four-point probing and delivers highly stable operation across a temperature range of 4.2 K to 475 K. Its high-precision micro-manipulators enable accurate positioning of probe tips, and the PS-100 can accommodate samples with a maximum diameter of 32 mm (1.25 inches). Boasting a compact benchtop footprint, the PS probe station is well-suited for academic and laboratory research, delivering efficient cryogenic operation via a continuous-flow refrigeration system that utilizes liquid helium or liquid nitrogen. Equipped with the matching Lake Shore Model 336 temperature controller, users can independently adjust the temperatures of the sample stage and radiation shield while monitoring the temperature of the probe arms.
