Membrane Filter 簡介1. Membrane filters or “membranes” are microporous films with specific pore size ratings. Membranes retain particles and microorganisms that exceed their pore ratings by acting as a physical barrier and capturing such particles on the surface of the membrane. 具有特定孔徑的微孔濾膜，能使微?；蛭⑸餃粼谀け砻妗Ｄさ莫?dú)特孔徑結(jié)構(gòu)具有截留顆粒的能力。 2. 孔徑和尺寸：圓片膜的常規(guī)孔徑為0.22m和0.45m，常規(guī)的直徑有13mm，25mm,37mm,47mm,90mm,142mm,293mm,其他的直徑和尺寸可以根據(jù)客戶的需要來提供。 3.
