Flow Rate | Life Science Research | Merck
Flow refers to the time it takes for a particular flow stream to pass through the filter. The flow rate of a filter is important in determining how rapidly filtration can be completed. This page describes how membrane and solute characteristics both affect flow rate. Although flow rate generally decreases with pore size among membranes of a single type, membranes with the same pore size rating, but made from different materials or by different methods, can have very different flow rates. Flow rate differences can be caused by differences in thickness, porosity, and pore architecture. -
