Question

Quizplus · Accepted Answer

Membrane filters are used for sterilization when heat sterilization is not appropriate. This is because many materials are destroyed by heat sterilization, and membrane filters offer a non-heat method for sterilization. The choice of filter pore size will depend on the specific application, but smaller pore sizes may be used to filter out smaller microorganisms. Membrane filters can be used to filter small and large amounts of liquid, depending on the size of the filter and the volume being filtered. While some materials may be difficult to filter with membranes, many fluids can be sterilized effectively through the use of membrane filters.
