At NINGBO INNO PHARMCHEM CO.,LTD., the production of high-purity bacteriostatic water for injection is a meticulously controlled process, designed to meet the exacting standards demanded by the pharmaceutical and research industries. As a leading manufacturer and supplier, our commitment to quality is embedded in every step, from raw material selection to final packaging. We understand that the integrity of your formulations depends on the purity and sterility of our products.

Our manufacturing process begins with the highest quality purified water, which undergoes multiple filtration and purification steps to remove impurities, ions, and microorganisms. This water is then combined with a precise concentration of a pharmaceutical-grade bacteriostatic agent, typically benzyl alcohol, to create our bacteriostatic water for injection. The exact formulation and concentration are critical and are maintained through rigorous process controls.

Sterilization is a key phase. The formulated bacteriostatic water is subjected to terminal sterilization methods, such as autoclaving, under precisely controlled conditions to eliminate any remaining microbial contaminants. Following sterilization, the water is aseptically filled into sterile vials. The filling process takes place in a controlled cleanroom environment to prevent any recontamination. Each vial is then sealed to maintain its sterility until it reaches the end-user.

Quality assurance is an ongoing commitment. Every batch of bacteriostatic water undergoes comprehensive testing. This includes testing for purity, sterility, endotoxin levels, and the correct concentration of the bacteriostatic agent. Certificates of Analysis are provided to confirm that our product meets all specified requirements. For those looking to buy bacteriostatic water, partnering with a manufacturer like us ensures you receive a product that adheres to the highest quality benchmarks. We are dedicated to being your reliable supplier, offering competitive pricing for bulk purchase and consistent product excellence.
