ProClin(TM) Preservatives

ProClin™ preservatives are water-soluble formulations of biocides that 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™ products help 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. Learn more about our ProClin™ products.

We provide ProClin™ biocide product range with different characteristic formulations in multiple pack sizes to suit your specific needs.
