Application

ProClin™ preservatives are immediately microstatic upon contact with microbial organisms as a result of their ability to quickly penetrate cell membranes and inhibit specific enzymes crucial to cellular respiration. Multiple specific sites of ProClin™ toxicity prevent microorganisms from developing high levels of resistance, making ProClin™ highly efficient even over extended storage periods of your IVD components.
