Sartorius, 13101--50----AHN, Cellulose Nitrate Membrane Filter, White, Non-Sterile, 8 Micro m
Features:
- The non-sterile membrane filters are made of cellulose nitrate (cellulose mixed ester), cellulose acetate or regenerated cellulose.
- They can be used for colony counting, particle testing and microscopy.
- The membrane filters are in accordance with the following norms: ISO 7704, ISO 7899-2, ISO 8199, ISO 9308-1 and EN 12780.
Non-sterile, gridded membrane filters can be used for colony counting, particle testing and microscopy. Before usage, the filters first need to be sterilized (e.g. by autoclaving at 121°C). Cellulose nitrate filters (mixed cellulose ester) contain a mixture of cellulose nitrate and cellulose acetate, which assures effective retention combined with high flow rates and optimal colony growth. Cellulose acetate combines high flow rates and thermal stability with very low adsorption characteristics.
