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.
Designed for non-optical experiments, the ST-200 includes the following components:
- Tubular vacuum shroud
- Tubular radiation shield
- Blank sample holder
- One (1) 10-pin electrical feedthrough
- Three (3) blank feedthrough ports
- Temperature sensor
- 6 ft superinsulated cryogen transfer line
- Control heater
- System test
Typical applications:
- High Tc
- Resistivity
- Hall studies
- Magnetoresistivity
- NMR spectroscopy
- Diffractions:
- Gamma ray
- Neutron (please see other configurations)
- X-ray

The ST-200-NMR standard configuration
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.
