You should pay attention to the problem when using the cryostat.

Shanghai Xinzhuang Instrument Co., Ltd. offers a low-temperature thermostat that is widely used in laboratories and industrial settings for precise temperature control. The device consists of several key components, including a compressor, condenser, evaporator, internal and external fans, a circulating water pump, a stainless steel inner tank, a heating element, and an intelligent temperature controller. These parts work together to maintain a stable and accurate low-temperature environment. The internal operating principle of the low-temperature bath follows a refrigeration cycle: after the compressor starts, it compresses the refrigerant gas, which then undergoes condensation, throttling, and evaporation. During evaporation, heat is absorbed from the surrounding medium, causing the water temperature to drop to the set value on the temperature controller. If the set temperature is higher than the ambient temperature, the contactor in the controller activates, sending a signal to the heating element to start working. This ensures the system maintains the desired temperature. The unit allows for both internal and external circulation of the water source. By connecting the inlet and outlet ports, users can create a secondary constant temperature zone outside the cryostat, making it suitable for various applications such as chemical reactions or sample cooling. To use the low-temperature thermostat, connect it to a 220V AC power supply with a rated current of at least 10A and ensure proper grounding. When adding water, make sure the level is at least 8cm below the top cover. Always use soft water, preferably distilled water, to avoid damaging the heating element due to mineral buildup. Hard water, such as well water or river water, should be avoided. Before starting, follow the instructions on the temperature control panel. First, turn on the power, then set the desired temperature according to the manual. Once the temperature reaches the set point, activate the circulation switch to begin normal operation. This ensures all functions are properly engaged and the system runs efficiently. **Precautions for Use:** 1. Ensure the power supply is 220V AC, 50Hz, and has sufficient capacity to support the entire unit. A reliable grounding system must be in place. 2. Fill the cryostat’s front compartment with the appropriate liquid medium. The liquid level should be about 30mm below the working platform to prevent damage to the heater when the power is turned on. 3. Choose the right liquid based on the working temperature: - For temperatures between 5°C and 85°C, use water. - For temperatures between 85°C and 95°C, use a 15% glycerin solution. - For temperatures above 95°C, use oil with an open cup flash point at least 50°C higher than the working temperature.
