Biosart® 100 Monitors
By Sartorius
The Biosart 100 Monitors are sterile, ready-to-use funnels used for colony counting. They have been specifically designed for microbiological testing of pharmaceuticals, food, beverages, water and other liquids. These sterile disposables with an incorporated membrane filter and cellulose pad are ready to use. After filtration, just remove the 100 ml funnel to convert the Monitor into a petri dish. Culture media for wetting the pad are available in individually sterilized, convenient plastic ampoules.
Biosart 100 Monitors ensures the identification of all colonies. The printed grid lines make the counting easier, especially for higher bacteria counts and microcolonies, without influencing microbial growth. The three various filter colors, green, white and gray (after wetting black), allow the best contrast to the colonies.
The Biosart 100 Monitors are made of polystyrene and supplied with an integrated pad and a 47mm diameter membrane filter which is available in .2, .45 or .8µm pore sizes. They are also composed of different materials such as cellulose nitrate and regenerated cellulose. Monitors with cellulose nitrate (cellulose ester) membrane assure effective retention with high flow rates and optimum colony growth. Monitors with regenerated cellulose membrane, a material which combines high flow rates with high chemical stability are ideal for bioburden testing in the veterinary sector, where a lot of products are based on solvents.
