Cryostat with liquid nitrogen cooling

A Cryostat with liquid nitrogen cooling is a vacuum-insulated vessel designed to cool samples to cryogenic temperatures, typically measured in Kelvin. This type of Cryostat is commonly used in scientific research and material testing where temperatures well below room temperature are required. It utilizes liquid nitrogen as the primary cooling agent, providing a cost-effective and efficient means to achieve temperatures down to 77 K, which is the boiling point of liquid nitrogen.

Product Features:

1. Cost-Effective Cooling: Liquid nitrogen is an economical choice for cooling, as it is relatively inexpensive and readily available. It offers a base temperature of 77 K, making it suitable for a wide range of applications that do not require ultra-low temperatures.

2. Temperature Control and Stability: The cryostat can be equipped with temperature controllers that use a PID loop to manage temperature ramping, minimizing overshoot and maximizing the efficient use of cryogens. This ensures precise temperature control and stability, which is crucial for accurate experimental results.

3. Ease of Use and Maintenance: Cryostats with liquid nitrogen cooling are straightforward to operate. They can be cooled by pouring liquid nitrogen into the bath, and the temperature is controlled by adjusting the flow of nitrogen through a heat exchanger.This system is also low maintenance, as it does not require complex mechanical coolers or frequent refills of cryogens.

4. Versatility in Operation: These cryostats can operate in various orientations, with the vertical position being the most cryogen-efficient. They can also be used with different cryogens, such as liquid helium for temperatures below 4.2 K, by adjusting the flow control valve.

5. Safety and Reliability: The cryostat is designed with safety features such as pressure relief valves and vacuum-tight electrical feedthroughs, ensuring that the system operates safely under vacuum conditions. The use of liquid nitrogen also reduces the risk of detector failure due to temperature cycling, as there is no risk of warm-up during power outages, provided that liquid nitrogen is maintained.
