Filters and membranes

Filters and membranes

Filters and membranes are distinguished by a pronounced porosity. The smallest pores in the through pore system are usually of decisive importance. Thus, depending on the particular tasks, either the total pore volume or all open pores can be determined, e.g. in the case of adsorption filters, or only the through pores which are relevant for the filtration process.
