Environment by Janis (only available from Lake Shore Cryotronics through QDUKI in the UK and Ireland) offers cryogen-free cryostats use both 10 K and 4 K cryocoolers, covering a temperature range of 1.5 K to 800 K. Choose from top- or bottom-loading designs suited for an extensive range of applications.
In addition to standard catalogue systems, Janis Research has complete custom design and fabrication capabilities. Their staff of physicists and engineers can design a system based on your specifications and requirements. They also maintain comprehensive records of previously built systems, and can often meet your requirements with an existing design.
LHe and LN₂ cryostats
The range has a full line of liquid helium and liquid nitrogen-cooled cryostats. Choose from continuous flow or reservoir cryostats, with many application-specific designs available. These include the …

Cryogen-free Cryostats
MODEL CCS-150
Standard, optical, sample in vacuum 10 K cryocooler with CTI cold head
The Janis CCS-150 is among the most versatile systems available for laboratory sample cooling. The system is equipped with f 1.0 optics and includes provisions for a wide variety of electrical connectors. Tapped mounting holes on the vacuum jacket and a sturdy refrigerator baseplate offer convenient mounting in any orientation. The CCS-150 is designed for measurements to 325 K.
The Model CCS-150 optical closed-cycle refrigerator was used in experiments mentioned in the following article, which appeared in APPLIED PHYSICS LETTERS 86, 081104 (2005).

See the Janis 10 K Cryocoolers product page
MODEL CCS-350T
Compact, non-optical, sample in vacuum 10 K cryocooler with CTI cold head
The Janis CCS-350T is designed for experiments where optical access to the sample is not needed. This systems includes provisions for a wide variety of electrical connectors, and a sturdy refrigerator baseplate offers convenient mounting in any orientation.
The compact CCS-350T offers the same large 1.5 in diameter sample mounting area as the standard model, but with reduced radiation shield and vacuum jacket diameters.
