ProClin Preservatives

ProClin preservatives are among the most effective biocides in the IVD industry, used in over 1,000 FDA registered IVD kits from industry leading diagnostic manufacturers. At low working concentrations, ProClin helps extend the shelf life of IVD reagents by effectively and immediately inhibiting a broad spectrum of microbes.

ProClin biocides attack the Krebs cycle at four key points: the enzymes pyruvate dehydrogenase, α-ketoglutarate dehydrogenase, succinate dehydrogenase, and NADH dehydrogenase. Because all bacteria and fungi possess at least part of the Krebs cycle, they are broad spectrum in their activity.



Unlike other biocides, ProClin preservatives present reduced health hazards, toxicology problems, and disposal issues at recommended usage levels. We offer four unique formulations, ensuring a variety of options to meet a wide range of specific needs. To learn more about our ProClin products click here

Despite the enhanced safety profile of ProClin products, a study from an independent lab have shown equivalent or improved efficacy when compared to top alternatives like thimerosal and sodium azide. To see this study, click here.

ProClin products are readily available in convenient pack sizes suitable for all manufacturing processes and volumes. The ProClin variety kit 48119-U contains 5 mL bottles of all four formulations and is an excellent tool to evaluate the suitability of ProClin products for their specific applications.
