Cell culture laboratories have extremely strict requirements on experimental environment and gas quality, and nitrogen generators specially used for cell culture have become key supporting equipment for cell culture, tissue engineering, and biopharmaceutical research. In cell culture experiments, high-purity nitrogen is mainly used for oxygen isolation and atmosphere protection of cell culture environment, preventing cell oxidation, microbial contamination and culture medium deterioration caused by air oxygen and impurity bacteria. Ordinary air contains a large amount of oxygen, water vapor and miscellaneous bacteria, which will lead to cell apoptosis, slow growth and experimental failure in the process of cell culture. The special nitrogen generator for cell culture laboratories can provide sterile, dry and high-purity nitrogen, build a stable anaerobic or low-oxygen culture atmosphere, and ensure the normal growth and reproduction of cells.

Cell culture laboratory nitrogen generators adopt food-grade and biological-grade purification standards on the basis of high-purity nitrogen production. The equipment is equipped with multi-stage sterile filtration and dehydration and oil removal systems, which can effectively remove bacteria, dust, water vapor and organic impurities in the air. The produced nitrogen has a purity of up to 99.99%, with zero bacteria and zero dust, fully meeting the aseptic and dust-free environmental requirements of cell culture rooms. Different from industrial nitrogen generators, this type of equipment has ultra-low impurity content and no secondary pollution in the gas production process, which will not produce toxic and harmful substances affecting cell growth. It is widely used in conventional cell culture, anaerobic cell culture, stem cell culture, and cell cryopreservation protection scenarios. In addition, the equipment has the characteristics of low noise, constant temperature gas production and stable gas volume, which will not cause environmental vibration and temperature fluctuation in the cell culture room, and avoid affecting the stable growth of cells. Compared with traditional bottled nitrogen, on-site nitrogen generators avoid bacterial contamination caused by cylinder pipeline connection and gas replacement, ensure the continuity and sterility of gas supply, and provide a safe and stable atmospheric environment for cell culture experiments, which is an indispensable core equipment for standardized biological cell culture laboratories.
