ProCide™ 150 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.
ProCide™ 200
ProCide™ 150 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 ProCide™ series of liquid preservatives penetrates microbial cell membranes efficiently, inhibiting respiratory-related enzymes and rapidly reducing microbial viability. When used at recommended levels, ProCide™ 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.

Instruction:
The recommended dosage for ProCide™ 200 Liquid Preservative is 0.06%–0.1% (w/w) of the final reagent concentration. For example, add 0.6–1 mL per liter of sample diluent.
When the working environment pH exceeds 8.5, ProCide™ 950 Liquid Preservative is recommended.

Q1: Which ProCide preservative should I choose for my reagent?
A: Match by use level and pH window: ProCide 300 is typically applied at 0.03-0.05% w/w and covers pH 2.5-8.5, while ProCide 950 and BIT-10 cover a wider pH range of 2.0-12.0; the series (150/200/300/950/1000) spans different actives and compatibility profiles - see the TDS tables for side-by-side comparison.
Q2: Can ProCide preservatives be used outside IVD reagents?
A: ProCide 300 and ProCide 950 also have application cases in personal-care and cosmetic formulations; contact us for regulatory and dosage guidance in those fields.
Q3: Do the preservatives affect protein-based reagents?
A: The series is designed for IVD liquid reagents and is compatible with antibody/antigen and enzyme systems at recommended use levels; confirm with your own stability studies.
Q4: What are BND-10 and BIT-10?
A: They are broad-spectrum liquid preservatives complementary to the ProCide line - BIT-10 covers a wide pH range, offering an alternative active for formulations where isothiazolinone-class preservatives are preferred.
Q5: Is technical support available for preservative selection?
A: Yes. Share your formulation and pH range with our technical team and we will recommend the most suitable grade and use level.
Q6: Is there an alternative to ProClin™-type preservatives for IVD reagents?
A: Yes - the ProCide™ series is a widely used alternative with comparable use levels: ProCide 300 is typically applied at 0.03-0.05% w/w over pH 2.5-8.5, while ProCide 950 and BIT-10 extend coverage to pH 2.0-12.0. Replace your current isothiazolinone-based preservative at the equivalent active concentration, then confirm microbial protection and reagent stability in your own challenge and stability studies. Our technical team can recommend the grade and dose for your formulation.
