The Janis ST-500-UC continuous flow cryostat has a very low profile (1.163”) and has been specifically designed for use in microscopy and imaging applications. The combination of low thermal-expansion support structure and internal vibration isolation results in low vibration and drift levels. The cryostat geometry offers a short working distance (for use with high magnification optics) between the top window and the sample.


Standard Configuration

The ST-500-UC system includes a flexible high-efficiency variable flow cryogen transfer line. This line delivers liquid helium or liquid nitrogen to the heat exchanger and sample mount. The ST-500-UC is portable, easily mounted in a variety of configurations, and can be used both in transmission and reflection geometries.
