Hall Measurement Systems

Our Variable Temperature Hall System (VTHS) allows the user to make automatic measurements of resistivity, mobility and carrier concentration of a wide range of samples using the Van der Pauw method over a temperature range from 70K to 730K. Sample mounting is simple and allows rapid interchange of samples.

Optical Studies Systems

This system is designed for Raman and fluorescence measurements to be made over a wide range of temperatures.

Seebeck Measurement Systems

Our SB-100 Seebeck Measurement System allows users to make automatic measurements of the temperature-dependent Seebeck potential of metals, semiconductors and other electrically conductive samples.

Variable Temp Micro Probe Systems

The Variable Temperature Micro Probe Systems, VTMP, (or Low Temperature Micro Probe Systems, LTMP) allow the user to probe devices mounted on the cold stage of a micro refrigerator.

Micro Miniature Refrigerators

Micro Miniature Refrigerators are small, cryogenic refrigerators that derive their cooling power from the Joule-Thomson expansion of a high-pressure gas. This effect is amplified by using the cooled gas to pre-cool incoming gas in a counter-current heat exchanger. Temperatures down to 70 K can be achieved in devices a little larger than a matchbox in size.

Kleemenko Cooler Systems

These low-cost refrigerator systems use a single-stream, throttle-expansion cycle of a mixture of refrigerants and have been used over the past decade to provide stable, maintenance-free temperature control between 65K and 150K.
