PC200

PC200 Liquid Preservative is one of the most widely used antimicrobials in the IVD industry, characterized by safety, environmental compatibility, and stability. It effectively suppresses bacterial and fungal growth by delivering broad-spectrum microbicidal activity, thereby helping extend the shelf life of IVD reagents. The PC200 series of liquid preservatives penetrates microbial cell membranes efficiently, inhibiting respiratory-related enzymes and rapidly reducing microbial viability. When used at recommended levels, PC200 preservatives are safe and eco-friendly, reducing health hazards, toxicological risks, and disposal concerns, while providing superior efficacy compared to traditional preservatives such as thimerosal and sodium azide.
