Membrane filter paper is the most needed materials when performing microbiological analysis of liquids by membrane filtration. The membrane filtration technique, which is one of the best methods used in the microbiological analysis of the liquid products, can perform analysis of larger volumes samples instead of 1-2 mL. Thus, it is possible to identify even if the sample contains very few microorganisms.
The basic principle of this technique is based on the retention of the microorganism in the material to be analyzed on the membrane filter. In the membrane filtration method, the bacteria in the filtered liquid sample cannot pass through the filter and are kept on the filter surface.
