The purpose of preservatives is to protect, by chemical means, products of various types against contamination by micro-organisms and thus against deterioration in quality. In principle, preservation is always required wherever water-containing organic products are stored at normal or elevated temperatures This is because microorganisms require, in particular, warmth, humidity and nutrients for growth. Preservatives are regulated and limits in use concentration have to be respected. Choose from Merck Millipore’s wide range of high-performance preservatives.
