Notices for Membrane Filter Operation

(1)In order to protect and prolong the service life of the filter membrane, filter paper or silk cloth of the same size can be placed on the filter membrane to prevent the rupture of the membrane filter.

(2)Measuring the foaming point: Measuring the pressure of the foaming point can reflect the pore size of the sterilized microporous filter membrane, which is closely related to the quality of the filtered liquid and an important means to ensure the quality of the sterilized microporous filter membrane.

(3)The sterile microporous membrane filter used should be immersed in water for injection at about 70 ~C for 1 hour in advance. After the water is poured out, the microporous membrane should be immersed in warm water for overnight reserve. When it is in use, it should be taken out and washed with water for injection, and then it can be put into the filter for use.

(4)The aperture is conical, the smooth side is small for the front, and the rough side is large for the reverse. When installing, the front (smooth side) should be facing up and the reverse (dark side) should be facing down.
