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.

Standard configuration

ST-300-MS supertran continuous flow cryostat

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.

This particular system is designed for use only with LN2, so there is no radiation shield in the sample area. The end-user only needs to remove the window block to access the sample and will never need to remove the entire vacuum shroud.
