ST-200 non-optical (tubular) cryostat

The ST-200 series are cryostats with tubular tails suitable for resistivity measurements or experimental configurations where square tails are undesirable.

Also available: the ST-200-NMR cryostat for NMR spectroscopy

We offer an application-specific variation of the tubular SuperTran ST-200 cryostat. This very specialized design includes a thermal anchor above the radiation shield for mounting electronics and a number of rotary and BNC electrical feedthroughs for access to the sample area.
