ProClin 150, 200, 300 is a broad spectrum antimicrobial suited as a preservative for in vitro diagnostic assays.[1] It does not inhibit most enzymes, antibody binding, nor interfere with ISE electrodes. ProClin is corrosive and can cause eye and skin burns, allergic skin reaction and dermatitis, may be harmful if swallowed, absorbed through skin, or inhaled (may be fatal as a result of spasm, inflammation and edema of the larynx and bronchi, chemical pneumonitis and pulmonary edema).

It is safe to dispose of at recommended use level. When disposing reagents containing ProClin 150, 200, 300, flush drains with copious amounts of water to dilute the components below biologically harmful levels (2ppm); many waste water handling systems can handle the ProClin levels, as is.
