The Membrane Filter (MF) Technique was introduced in the late 1950s as an alternative to the Most Probable Number (MPN) procedure for microbiological analysis of water samples. USA
Is the advantage of using membrane filter technique? Membrane filtration includes fewer processing steps and makes it possible to achieve both a greater degree of purity and higher overall yields. In addition, because membrane filtration does not result in a filter cake, there are no costs associated with the removal and disposal of this residue.
Membrane filtration technology provides an alternative to centrifugation. The patient's blood is pumped through a parallel-plate or hollow-fiber filter at a continuous flow rate, typically 50 to 200 mL/min (see Fig. 12-1B ). The membranes usually have pores of 0.2- to 0.6–μm diameter, sufficient to allow passage of plasma while retaining cells.
