The Biosart® 100 Monitors have been specifically designed for the detection and enumeration of microorganisms potentially present in pharmaceuticals, cosmetics, food, beverages, water and other liquids. The monitors are ready-to-use sterile funnels, due to the incorporated membrane filter and cellulose pad. After filtration, just remove the 100 ml funnel to convert the monitor into a petri dish, eliminating the need of membrane manipulation.
