Environment by Janis: Spotlight on Cryostats

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, Lake Shore’s cryostats have 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.

SuperTran Cryostat Continuous Flow Cryostat

Features:

• <2 K to 500 K (700 K option) operating range (model dependent)
• Easily adaptable to an RGC4 recirculating gas cooler for cryogen-free operation
• Can use either LHe or LN₂
• Sample-in-vacuum configuration
• Variable temperature sample mount and holder, with temperature regulated with a calibrated sensor and external temperature controller for precise sample temperature control
• Can be fitted with optical or non-optical tails
• The optical version has 4 window sets for measurement from UV to IR
• Optional cabling for electrical measurements
• Choice of cryocooler to match performance and budget requirements
• FTIR, ESR, NMR, microscopy, compact, and ultra-high vacuum models are available
• Highly flexible transfer line (12 in bend radius)
• Easy sample access

Lake Shore Cryotronics offers 10 K closed-cycle refrigerator (CCR) systems in a variety of configurations. Standard models include optical, non-optical, compact, subcompact, and rotatable vacuum shroud. The CCS-150 to 350 cryostat range starts at just £10,000+, making these an accessible and affordable option for your lab.

Some typical applications include:

• Cryogenic gas trapping
• Large sample volume (see Other configurations)
• Matrix isolation
• Neutron bombardment
• Neutron scattering
• UHV sample environment
• Vibration isolated systems for microscopy

Cryogen-free Cryostats

Lake Shore’s Environment by Janis 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.

These Lake Shore closed-cycle refrigerator cryostats cool the sample in vacuum and are bottom-loading. With a wide range of electrical feedthrough and window options, they are a versatile choice for making cryogenic measurements without using liquid helium.

Every cryostat comes with a Lake Shore temperature controller and calibrated sensor
