เมมเบรน ฟิลเตอร์
The pore size of membrane filters is indicated by testing in three different ways.For example,Microorganism sampling (actual filtration for microorganism),Porosimeter(measuring changes of air pressure on filters/air flow) and Bubble point (pressure when air emits through a pore size of a wet filter)
