Membrane filters are available in a wide choice of colors, pore sizes, either gridded or non-gridded, in individually sterile-packaged or non-sterile-packaged versions, and with or without a hydrophobic edge. The Microsart® e.motion membrane packaging is specially designed for use with the Microsart® e.motion Dispenser.
Cellulose nitrate, cellulose acetate or regenerated cellulose filters for colony counting, particle testing and microscopy
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. Choose between gridded or non-gridded, membranes, either with or without hydrophobic edge.
Overview
Cellulose nitrate, type 114, 0.2µm, white|black,50 mm, 100 membranes per box
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). The membrane filters are available in different pore sizes and three different material types. 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. The various filter colors allow the best possible contrast to the colonies or particles for easy and reliable quantification and identification.
