JEOL: Release of Cryogen Reclamation System

- Substantially reduces the evaporation of liquid helium used in the superconducting magnet for NMR -

TOKYO--(BUSINESS WIRE)--JEOL Ltd. (TOKYO:6951) (President & CEO Izumi Oi) announces launch of a new Cryogen Reclamation System for Nuclear Magnetic Resonance (NMR) on April 14, 2023.
This product was jointly developed by JEOL Ltd., a manufacturer of NMR instruments, Japan Superconductor Technology, Inc. (JASTEC), a manufacturer of superconducting magnets, and Ulvac Cryogenics Inc. which has strengths in cryogenic technologies, by combining the cutting-edge technologies of each company.
It can substantially reduce evaporation of both liquid helium and liquid nitrogen that are inevitable as cryogen for the NMR instrument’s superconducting magnet.

Main features

1. Light-weight and space-saving. Still, this system alone can reduce the evaporation loss of both liquid helium and liquid nitrogen.
2. It reduces the frequency and costs for refilling the cryogen and maximizes the operation time of the NMR instruments.
3. It can significantly reduce the risk of stopping NMR instruments due to difficulty in obtaining liquid helium.
4. The new design sufficiently reduces the vibration of the refrigerator and thus avoids affecting the quality of the spectrum.
5. Attachment is possible to the existing NMR instruments with the magnetic field maintained.
