Pharmaceutical Grade Stainless Steel High-Purity Nitrogen Generator

The 21st century is the era of biotechnology, nanotechnology, and electronic information technology. The requirements for the purity of process gases are extremely stringent in areas such as microelectronic devices, pharmaceuticals, biotechnology products, and instruments. The purity of process gases is crucial for improving the yield of electronic products, pharmaceutical products, and more. Nitrogen has a wide range of applications in the pharmaceutical industry, including protection in synthetic drug production, pneumatic conveying, isolation with pure nitrogen in bioengineering, and nitrogen purging and sealing in formulation production.

Pharmaceutical production imposes high demands on nitrogen
1. High purity of nitrogen is required, generally 99% to 99.99%.
2. Nitrogen must be free of dust and pyrogens, making it suitable for the filling and sealing of injections.
3. Nitrogen must be supplied at a constant pressure during the production process to ensure smooth operation.
Currently, the vast majority of formulation production in China, whether for large-volume infusions, injections, freeze-dried preparations, oral liquids, or other processes requiring nitrogen purging, relies heavily on nitrogen from cylinders produced through industrial nitrogen generation. The use of cylinders involves frequent transportation, loading, and unloading, occupies significant space, poses safety risks, and cannot provide continuous gas supply. Although some facilities undergo simple post-treatment, the nitrogen still falls far short of the purity and cleanliness requirements stipulated by the GMP standards for pharmaceutical production. Especially for injections requiring nitrogen purging, the quality requirements for nitrogen are even higher, as the quality of nitrogen directly impacts the quality of the final product.
Hangzhou Lecheng Gas Company, drawing on decades of expertise in producing pressure swing adsorption nitrogen generators, has collaborated with relevant research and production units to conduct secondary development and design, successfully developing the NC-B series of high-purity pharmaceutical nitrogen generators. A compact, specialized nitrogen generator can provide a continuous and stable supply of high-purity pharmaceutical nitrogen, eliminating the hassles of cylinder transportation, loading, unloading, and post-treatment, while further enhancing the purity and cleanliness of the nitrogen. The high-purity nitrogen produced by this machine fully complies with GMP requirements, making it an ideal nitrogen source for the pharmaceutical industry.
