Lake Shore Janis SuperVariTemp system

SuperVariTemp Cryostat Systems

The Lake Shore SuperVariTemp (SVT) system is the basis for a variety of variable temperature cryostats. Offering quick sample exchange, an operational range of 1.5 K to 300 K, and highly efficient operation, this versatile system is often incorporated into our CNDT Series Dewars or, for maximum flexibility, this concept is applicable to virtually any Dewar.

By controlling the temperature of the flowing helium vapour in which samples are immersed, both the sample and holder are simultaneously cooled to the same temperature, thereby eliminating the need for thermal anchoring and sample mount heating. The helium flow rate and heater current are balanced to provide flowing vapour/sample temperatures over the range of 1.5 K to 300 automatic temperature controllers together with application-specific thermometry provide accurate and precise temperature control.
