Janis - Recirculating Gas Coolers Now Available

Janis Recirculating Gas Coolers
March 2022

Quantum Design UK and Ireland is delighted to announce the arrival of the Janis Research (a Lake Shore company) Recirculating Gas Cooler to the UK and Ireland market.

The Janis SuperTran product line has long been an industry standard for continuous flow cryogenic systems. Now, with the introduction of the Janis recirculating gas cooler these cryostats can be cooled without the need for liquid cryogens.

Typical applications include micro-PL, micro-Raman, and high spatial resolution imaging. The Model RGC4 pulse tube-cooled system can also be used with the ST-100 optical workhorse, the ST-200 non-optical system, the ST-300 compact unit for use in a magnet, the ST-400 UHV configuration, the ST-500 microscopy configuration, and the ST-500 based probe station.

• All the flexibility and convenience of a continuous flow cryostat without liquid helium
• Fast sample change without warming up the RGC4 cooler
• Excellent thermal performance
• Low vibration — vibration data available upon request
• Compatible with most existing SuperTran cryostats
• Order a new cryostat with a transfer line and choose to operate using LN2, Lhe, or
