Degassing and filtration products are used for drug solution clarification, sterilization, pyrogen removal, protein/vaccine separation and purification, and the sterile, pyrogen-free, and impurity-free treatment of process water (purified water, water for injection), strictly complying with GMP standards. Simultaneously, CO₂ in process water is controlled to optimize pH and conductivity.
 
Common Issues:
 
Microbial/pyrogen/particulate contamination leading to product non-compliance or safety risks.
Excessive CO₂ causing pH fluctuations and decreased deionization efficiency.
Impuric residues affecting drug stability and efficacy.
 
Main Functions of Degassing and Filtration Products:
 
Highly efficient sterilization and impurity removal: Removes bacteria, pyrogens, particles, and organic impurities, ensuring GMP-grade purity of drug solutions and process water.
