STVP-200-NMR cryostat for NMR spectroscopy
Similar to the standard STVP-200 tubular system, but custom-designed for NMR spectroscopy.
STVP-200-NMR datasheet
Standard configuration
The non-optical SuperTran-VP (STVP-200) cryostat for NMR spectroscopy maximizes the internal sample space while still minimizing the cryostat outside diameter, providing a large 64 mm (2.5 in) sample space while fitting within an 89 mm (3.5 in) bore magnet. (Customized solutions are also available and can include a smaller outer diameter to fit small-bore magnets, or an increased sample chamber diameter to accept larger probes.)
Options include:
- Isothermal zone sample tube (provides uniform sample temperature and enhanced operation with LN2)
