Ultra-Low-Temperature applications

Ultra-Low-Temperatures(ULT) refer to temperatures below 1 Kelvin. There are two types of scientific instruments used for ULT applications:

  • Helium-3 or 3He refrigerators: typically achieving 300 mK base temperature
  • Dilution refrigerators: achieving temperatures in the range 25 -10 mK depending on model

These refrigerators can be integrated into superconducting magnets for applications requiring a combined B-T environment.

In recent years Helium-3 and dilution refrigerators have become available as Cryofree or cryogen-free. This offers new level of convenience and also simplifies their mode of operation. For more information on the product range available please vist the product section on 3He refrigerators and Dilution refrigerators.

The extensive range of electrical and sample access options allow applications such as fractional quantum Hall effect, soft X-ray detection or quantum computing studies. The versatility of sample environments, whether in liquid or vacuum, enables techniques requiring large heat load dissipation, such as
microwave excitation or solid state NMR, to be performed under the optimum thermodynamic conditions. Our products are designed to suit the most demanding applications.
