Fluids that could be ruined by warmth, irradiation or chemical sterilization, for example drug solution, is usually sterilized by microfiltration working with membrane filters. This method is commonly employed for warmth labile pharmaceuticals and protein alternatives in medicinal drug processing. A microfilter with pore dimension of generally 0.22 µm will proficiently clear away microorganisms.[sixty four] Some staphylococcal species have, nevertheless, been shown to get adaptable adequate to pass through 0.
