Technical advantages of laboratory liquid nitrogen machines

　　High-purity nitrogen gas is continuously generated using gas chromatography separation. Gas supplied by an air compressor pump is introduced into a molecular sieve, where oxygen, carbon dioxide, water, and other impurities are removed. Only nitrogen gas is allowed to pass through the molecular sieve into the gas tank. After adjusting to the appropriate pressure and flow rate, it can be used directly. This is the working principle of the laboratory liquid nitrogen generator. Now, let's learn aboutLaboratory Liquid Nitrogen Generatorits technical advantages.

　　I.Laboratory Liquid Nitrogen GeneratorTechnical Advantages:

　　1. Simple operation of the laboratory liquid nitrogen generator

　　Eliminates the labor and difficulty of cylinder handling. Nitrogen gas is generated simply by turning on the power switch, allowing for continuous or intermittent use. The nitrogen volume is stable and does not attenuate.

　　2. High Technology

　　The electrolytic cell uses a vertical single-layer double cathode.Laboratory Liquid Nitrogen GeneratorNew membrane separation technology uses PCA carriers and noble metal catalysts in the catalyst layer, improving the catalytic efficiency of the electrolytic cell, resulting in high output and high nitrogen purity. After more than 100 hours of high-pressure, high-current aging tests, the performance and operating status of the electrolytic cell are very stable.

　　3. Low Nitrogen Humidity

　　Laboratory Liquid Nitrogen GeneratorUsing high molecular weight permeation separation technology and an effective dehumidification device, the original humidity can be reduced, and automatic drainage occurs after shutdown. Metal polymer dehumidification and two-step adsorption significantly improve nitrogen purity.

　　4. Program Control

　　The mechanical control system uses a chip. All working processes are program-controlled. Automatic constant pressure, constant current, and nitrogen flow rate can be fully automatically adjusted according to the Applications, ranging from 0-300ml/min.

　　5. Three-level Catalyst

　　In addition to the secondary catalyst in the electrolytic cell, there is also a tertiary catalyst. Because the catalyst is a new type of noble metal,Laboratory Liquid Nitrogen Generatorthe output nitrogen gas oxygen content is less than 3ppm.

　　II. After using the laboratory liquid nitrogen generator for some time, it is found that the silica gel in the drying tube changes color from bottom to top. Replace the silica gel once it exceeds a certain height. The process is as follows:

　　1. Rotate the dry cap in the direction shown in the image until it is fully rotated. Do not perform this operation when there is pressure.

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

　　3. Add new (or dry) silica gel; do not exceed the small vent hole near the nozzle. Cover with cotton, cotton gauze, or other debris; do not bury it in the end face of the drying nozzle. Then, insert the inner tube into the outer tube of the drying tube.

　　4. Cover the drying tube cover, check for leaks with soap solution, and then start the machine.

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