Wide variable temperature range
Supports 65 K–800 K operation with precise control, covering a broad spectrum of experimental requirements.
Cryogenic Systems
Liquid Nitrogen Cryostat
Wide 65 K–800 K temperature range, fast cooling and stable vacuum environment for optical, electrical and magnetic experiments.
Product Overview
Dexinmag Liquid Nitrogen Cryostat provides a wide temperature range (65 K–800 K), high efficiency, fast cooling speed and a stable experimental environment, making it a preferred low‑temperature platform for many scientific research experiments.
Based on the steady‑state bubble principle, liquid nitrogen is stored in the cryostat tank. By adjusting the cone air plug clearance and changing the boiling condition of the gas–liquid interface, the heat leakage of the constant temperature block is stabilised while precise heater control enables rapid temperature change.
The system offers high cost‑effectiveness, compact structure and strong expandability for integration into optical, electrical, magnetic and thermal measurement systems.

Product Overview
Dexinmag Liquid Nitrogen Cryostat provides a wide temperature range (65K–800K), high efficiency, fast cooling speed and a stable experimental environment. It has become a preferred low-temperature equipment choice for many scientific research experiments.
The system is based on the steady-state bubble principle. Liquid nitrogen is stored in the cryostat tank, and by adjusting the cone air plug clearance and changing the boiling condition of the gas–liquid interface, the heat leakage of the constant temperature block can be stabilised.
The heating power is adjusted by the temperature controller so that the sample stage can change temperature rapidly between 65K and 800K and stabilise precisely at the set temperature. Main advantages include high cost-effectiveness, compact structure and strong expandability.
