ST-300-MS Compact Cryostat for Microscopy
Designed as an alternative to the ST-500 microscope cryostat, this compact cryostat combines short working distance with the standard SuperTran design. The ST-300-MS is intended for use in experiments with very tight space restrictions, and is available with a compact or ultra-compact window block.
Designed as an alternative to the ST-500 microscope cryostat, this compact cryostat combines short working distance with the standard SuperTran design. The ST-300-MS cryostat is intended for use in experiments where space restrictions do not allow the use of the ST-500. While this cryostat does not have the ultra-low vibration and thermal drift characteristics of the ST-500 cryostat, the vibration levels are still submicron.
As with all SuperTran cryostats, the ST-300-MS system includes a flexible high-efficiency variable flow cryogen transfer line that delivers liquid helium or liquid nitrogen to a two-stage heat exchanger and sample mount. The ST-300-MS is portable, easily mounted in a variety of configurations, and can be used both in transmission and reflection geometries. The sample holder position is adjustable to allow for samples of varying thicknesses.
