Sample is often inoculated through the testing laboratory a result of the will need for preprocessing actions for membrane filtration.

When there is the existence of any microorganisms, then it really is retained in the filter. Under the aseptic situation, filter in the membrane. Then aseptically take away the membrane and Lower it into two halves.
