Scryo® S-300 Compact Microscope Cryostat
Scryo®S-300 (abbreviated as S-300) is a compact continuous-flow open-loop micro cryostat featuring specialized temperature drift compensation combined with a robust ultra-insulation support structure, enabling ultra-low vibration and ultra-low drift performance. The ultra-compact form factor is specially designed for experimental scenarios with limited space. It can be installed either vertically or horizontally, and easily matched with commercial spectrometers and microscopes for experiments such as absorption, transmission, reflection, spectroscopy, and microscopic confocal. It can also be readily paired with electromagnets and room-temperature bore superconducting magnets for magneto-optical testing, and is widely used in experiments like X-ray, high-energy, and high-pressure applications.
The S-300 compact micro cryostat incorporates an efficient vaporizer combined with ultra-insulation transfer lines, featuring rapid cooling speed and low refrigerant consumption. The S-300 cryostat combines with the helium circulation cryogenic system (Qcryo®) to form a dry, closed-loop microscopic cryogenic system (Qcryo-S-300) that does not consume liquid helium, maintaining the ultra-low vibration and drift characteristics of the open-loop operation mode.
The S-300 compact micro cryostat offers various optional accessories, including windows for multiple wavelength bands, multiple vacuum feedthroughs, cables, and sample holders, with optional stainless steel vacuum casing and indium-sealed flanges.

Note：1.The minimum temperature is based on tests of the standard S-300 cryostat without external heating loads. 2.When using liquid helium as the cold source, the minimum temperature is closely related to the pumping speed of the vacuum pump. 3.When using Qcryo® as the cold source, the minimum temperature is related to the cooling capacity of the cold head and the pumping speed of the circulation pump. | |
The following figure shows the typical cooling time of the dry closed-loop microscopic cryogenic system (Qcryo-S-300). The initial cooling time from room temperature to 4K is less than 3 hours, with the minimum temperature below 2K, while maintaining the ultra-low vibration and drift characteristics of the open-loop operation mode. The cooling time after sample replacement is less than 1.5 hours.
