ST-300 & ST-300T Compact Cryostats

Designed for experiments with limited space, these cryostats are available in optical or non-optical configurations. The tail diameters can be specified to fit your experiment.

Standard configuration

Designed for experiments with limited space, the Janis Research ST-300 optical and ST-300T include the following components:

Optical (ST-300)

  • Compact optical vacuum shroud

  • Optical 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

Tubular (ST-300T)

  • Compact tubular vacuum shroud (1.5 in O.D.)
  • Compact 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:

  • Microscopy
  • Narrow gap magnet
  • Spectroscopy
  • Hall studies
