Liquid nitrogen storage thermostat
Liquid nitrogen storage cryostat offers a wide temperature range from 78 K to 500 K (800 K optional, with pump-down down to ~65 K). Samples are cooled in a vacuum using heat conduction. The large sample compartment accommodates a variety of sample holders, allowing testing of a wide range of thin films, bulk materials, powders, and liquid samples. The 0.4 L liquid nitrogen storage capacity maintains low temperatures for up to 5 hours, and liquid nitrogen can be refilled without disrupting the experiment.
The liquid nitrogen storage cryostat comes with a built-in 0.4L liquid nitrogen storage capacity, which can be easily refilled through the top refill port without affecting the system's temperature control. The cryostat features a liquid nitrogen flow control lever for adjusting the cooling capacity. A built-in heater and temperature sensor work in conjunction with an external thermostat to provide variable temperature control. The liquid nitrogen storage cryostat offers continuous temperature control from 65K to 800K, greatly facilitating scientific experiments requiring both low and high temperatures. The sample chamber features a quick-release clamp design, allowing for quick access when changing samples. To meet customer electrical testing needs, the cryostat can be configured with various electrical leads (such as Ph-Br wires, coaxial and triaxial cables), resistor sample holders, and probe sample holders. The cryostat comes standard with four clear quartz windows, transmitting wavelengths from the ultraviolet to the near-infrared. Other window materials are available to accommodate testing across a wide spectral range, from the far/mid-infrared, ultraviolet, and X-rays.

Closed-loop thermostat
The 4K series closed-circuit thermostats offer a wide temperature range from 4 K to 325 K (500 K or 800 K optional). Samples are kept in a vacuum and cooled by heat conduction. They feature ample sample space and can be combined with a variety of sample holders to test a variety of thin films, bulk materials, powders, and liquids. Four optical windows are standard.
Closed-loop thermostat
The 1.5K series closed-cycle cryostats offer continuous temperature control from 1.5K to 325K. They feature ample sample space and can be fitted with a variety of sample holders, enabling testing of a wide range of thin films, bulk materials, powders, and liquids. The aluminum vacuum housing and radiation shield feature a segmented design for fast sample changes. Equipped with a closed-cycle refrigerator, the built-in heater and temperature sensor work in conjunction with an external thermostat to achieve temperature control.
Continuous Flow Thermostat
The continuous flow thermostat can achieve a wide temperature range: from 4K to 450K, and can reduce the temperature to ~2K. The sample is in a vacuum and is cooled by heat conduction. The sample space is large and can be equipped with a variety of sample holders to test various thin films, blocks, powders and liquid samples. The refrigerant consumption is low. Using liquid helium to cool from room temperature to 5K only consumes 0.4L of liquid helium, and using liquid nitrogen to maintain 80K consumes 0.1L/h. It comes standard with 4 optical windows.
