 Laboratory Liquid Nitrogen GeneratorWhat are the advantages? What is the process for replacing the silica gel?

 Oxygen, carbon dioxide, water, and other impurities are removed by the molecular sieve. Only nitrogen gas is allowed to pass through the molecular sieve and enter the storage tank. After adjusting the appropriate pressure and flow rate in the storage tank, it can be used directly. This is the working principle of the laboratory liquid nitrogen generator.

　　I.Laboratory Liquid Nitrogen GeneratorTechnical Advantages

　　1. Simple Operation

　　It avoids the labor of transporting cylinders, eliminating the hassle of cylinder transportation. Simply turn on the power switch to generate nitrogen gas. It can be used continuously or intermittently, with stable nitrogen gas output and no attenuation.

　　2. High-Tech

　　The electrolyzer adopts a vertical single-layer double-cathode design. The new membrane separation technology uses a PCA carrier and a noble metal catalyst in the catalyst layer, improving the catalytic efficiency of the electrolyzer, resulting in high yield and high nitrogen purity. After more than 100 hours of high-pressure, high-current aging tests, the performance and operating status of the electrolyzer are very stable.

　　3. Low Nitrogen Gas Production Humidity

　　The laboratory liquid nitrogen generator uses high molecular weight permeation separation technology and an effective dehumidification device to reduce the original humidity and automatically drain after shutdown. Using metal polymer dehumidification and two-stage adsorption significantly improves nitrogen purity.

　　4. Program Control

　　The machine's control system uses a chip. All working processes are completed by program control. Automatic constant pressure, constant current, and nitrogen flow rate can be automatically adjusted to 0-300ml/min according to usage.

　　5. Three-Stage Catalysis

　　In addition to the secondary catalyst in the electrolyzer, there is another three-pole catalyst that uses new noble metals to make the oxygen content of the nitrogen output less than 3pm.

　　After using the liquid nitrogen generator in the laboratory for a period of time, it was found that the silica gel in the drying tube changed color from bottom to top. Once it exceeds a certain height, the silica gel needs to be replaced. The procedure is as follows:

　　1. Turn the drying cap in the direction shown in the picture until it is fully rotated. Strictly prohibit this operation if there is pressure.

　　2. Remove the inner tube from the main tube upwards, take out the cotton swab, and pour in the silica gel.

　　3. Carefully add new (or dry) silica gel, ensuring it does not exceed the small vent hole near the nozzle. Do not bury cotton, gauze, or other debris in the end face of the drying nozzle (otherwise it will leak). Then, insert the inner tube into the outer tube of the drying tube.

　　4. Tighten the drying tube cap and start the machine after checking for leaks with soapy water.

 5. The replacement method for activated carbon is the same as for silica gel.
