Low-temperature cycle equipment operation importance description

The use of low-temperature cycle equipment is inseparable from its standard operation. LNEYA low-temperature cycle equipment will be shipped with the corresponding instruction manual, and users can know ahead of time when using it.

The low temperature circulation equipment, also known as the low temperature constant temperature bath, is a high precision constant temperature source with its own refrigeration, and has the function of a small chiller. Widely used in petroleum, chemical, metallurgy, pharmaceutical, biochemical, physical properties, testing and chemical analysis and other research departments, institutions of higher learning, factory laboratories and metrological quality inspection departments. According to the different opening size of the low-temperature cycle equipment, the constant temperature experiment can be carried out in the equipment, or it can be connected with other equipment through the hose and used together with the constant temperature source.

Low temperature cycle equipment should be used when the medium is used. When the working temperature of the medium in the equipment is relatively low, an aqueous solution of ethylene glycol or absolute ethanol is generally used. When the working temperature is 5 ° C to 80 ° C, deionized water is generally used. When the operating temperature of the low temperature cycle equipment is 80 ° C to 98 ° C, a 15% glycerin aqueous solution is generally used.

Low-temperature cycle equipment uses working power: 220V/50Hz, the power supply should be greater than the total power of the instrument, the power supply must have a good "grounding" device, use liquid medium in the low-temperature cycle equipment, the liquid level of the medium should be lower than the working table 30mm, Otherwise, the heater will be damaged when the power is turned on. When the temperature is higher than room temperature, please turn off the cooling, and the temperature inside the device can be completely controlled. Do not use ethanol when the temperature of the low-temperature cycle equipment is higher than 30 °C, so as to avoid danger. (Because of the high rate of volatilization at high temperatures, it is prone to danger).

The low-temperature circulation equipment should be placed in a dry and ventilated place, and there is no obstacle in the 300mm around the instrument. When the working temperature of the equipment is high, care should be taken not to open the upper cover, and do not enter the tank to prevent burns. After use, all the switches are turned off, the power is cut off; the cleaning work is done, and the work surface and the operation panel are kept clean.

Different manufacturers may have slightly different differences, so users need to know about the low-temperature cycle equipment they purchased. If you are not sure, you can contact the relevant manufacturers to obtain relevant information.
