Open-Flow Coolers

Enhance Your Structural Analysis with Precision Cryogenics

Open-Flow Coolers are specialized devices used in scientific research to provide precise temperature control for cooling or heating samples. They are employed in a range of applications, including materials research, Micro-CT, and crystallography; any field where an x-ray or electron beam is used to investigate a sample’s structure.

These devices are unique in their ability to deliver a carefully calibrated laminar flow of dry gas, known as the “gas shield,” which provides insulation, safeguarding your sample from the local atmosphere and enabling the sample area to reach extremely low temperatures without the interference of ice formation.

Various techniques are used to achieve the desired temperature, ranging from heating liquid nitrogen to mechanically cooling nitrogen gas and helium. The methods used by our open-flow coolers have different applications, and all of them ensure the sample area is maintained at a highly precise and stable temperature, facilitating accurate and reliable experimental results.
