Use membrane filters of the suitable material having a pore measurement of 0.45 µm or much less. Filters about fifty mm across are recommended, but other measurements can be utilised. Sterilize the filters, filtration apparatus, media, as well as other apparatus made use of. Ordinarily, measure two test fluids of ten ml Each and every; go Each and every sample through a different filter. Dilute the pretreated test fluid Should the micro organism focus is significant, making sure that 10 a hundred colonies can create per filter. Immediately after filtration, wash each filter thrice or more with an proper liquid such as phosphate buffer, sodium chloride- peptone buffer, or fluid medium.
