Lake Shore Janis SuperTran-VP NMR Cryostats
SuperTran-VP Cryostat Systems
Lake Shore SuperTran-VP STVP-NMR nuclear magnetic resonance cryostats are optimised for NMR magnets with an 89 mm (3.5 in) diameter bore; custom configurations can be fabricated for larger or smaller magnets. Samples are typically mounted in a user-supplied NMR insert, which is mounted inside a 55 mm (2.17 in) inner diameter chamber. An isothermal zone sample tube provides uniform sample temperature and enhanced operation with LN2.
STVP-NMR cryostats can be combined with Infinite Helium for cryogen-free operation throughout the entire temperature range. This enables unattended cryostat operation, ideal for extended duration measurements.
Every cryostat comes with a Lake Shore temperature controller and calibrated sensor 
FEATURES
- 30 min cooldown to 5 K
- Sample in flowing vapour for uniform sample cooling
- Easy sample access with top-loading sample chamber
