Non-sterile grid membrane filters can be used for colony counting, particle testing and microscopy. For use, the filters must first be sterilised (e.g. by autoclaving at 121°C). The membrane filters are available in different pore sizes and three different material types. Cellulose nitrate filters (cellulose mixed ester) contain a mixture of cellulose nitrate and cellulose acetate, guaranteeing effective retention combined with high flow rates and optimal colony growth. Cellulose acetate combines high flow rates and thermal resistance with very low adsorption properties. The different filter colours allow the best possible contrast against colonies or particles for easy and reliable quantification and identification. Also available with high-flow filters Three different colours available The membrane filters comply with the following standards: ISO 7704, ISO 7899-2, ISO 8199, ISO 9308-1, DIN EN ISO 11731-2 and EN 12780.
