JEOL: Release of Cryogen Reclamation System
– Substantially reduces the evaporation of liquid helium used in the superconducting magnet for NMR –
TOKYO — 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.
- Light-weight and space-saving. Still, this system alone can reduce the evaporation loss of both liquid helium and liquid nitrogen.
- It reduces the frequency and costs for refilling the cryogen and maximizes the operation time of the NMR instruments.
- It can significantly reduce the risk of stopping NMR instruments due to difficulty in obtaining liquid helium.
- The new design sufficiently reduces the vibration of the refrigerator and thus avoids affecting the quality of the spectrum.
- Attachment is possible to the existing NMR instruments with the magnetic field maintained.
- Boil-off performance
Liquid helium : Zero Boil Off (nominal)
Liquid nitrogen : Zero Boil Off (nominal)
