• Is your need for temperatures up to 700 K or higher?

  If you are probing wafers and devices in high vacuum and cryogenic environments, check our vibration isolated micromanipulated probe systems and fixed probe systems that operate up to 700 K or higher. These include options for using nanoscale translation stages that are built into the cryostat for the ultimate in precise measurements and temperature control.

   

   

   

• Is your need for temperatures down to 4 K?

  If you would like to avoid liquid cryogens, inquire about our low vibration pulse tube refrigerated systems offering temperatures down to 4 K. These are offered with our own designed high conductive flexible copper links that practically eliminate any temperature gradients between the cold head and the experimental cold stage.

   

   

• Is your need for temperatures down to 2.5 K?

  If you require temperatures down to 2.5 K, Janis Research offers continuous flow ST-400 systems (shown far left) that offer UHV clean environments and ultra low loss transfer lines for operation at very low (nanoscale) vibration levels. If you require optical access, you can check our ST-500 cryostats (shown near left) with ultra low drift stages, ideal for use with laser scanning con-focal microscopes.

   

• Is your need for temperatures down to 1.5 K or 1 K?

  If you need temperatures down to 1.5 K or 1 K, check our variable temperature SVT & 1 K pot cryostats that can be used with AFM, SNOM and other scanning probe microscopes. These are available in clean high vacuum and UHV environments, with optical and magnetic field options. They are also available with ultra low loss cryostats that offer boil off rates of 4 to 5 liters per day, including superconducting magnet support and high current leads.

• Is your need for temperatures below 300 mK?

  If your need is below 300 mK, Janis He-3 refrigerators may fulfill your requirements. One system of interest is Model HE-3-TLSL, which is top loading with sample in liquid.

   

   

   

   

   

   

• Is your need for temperatures below 50 mK?

  If your need is 50 mK, Janis Adiabatic Demagnetization Refrigerators (ADR) may fulfill your requirement. Janis offers a liquid helium cooled system and a cryogen-free system. These systems are based on a patented NIST design.

   

   

• Is your need for temperatures to 25 mK or lower?

  If you need 25 mK or lower, Janis Dilution Refrigerators (DR) may fulfill your requirement.
