Microporous filter membrane nylon membrane

0.45 μ m conventional sample, mobile phase filtration, can meet general chromatographic requirements

0.22 μ m is required to remove extremely fine particles from samples and mobile phases

1-5 μ m is used for difficult to handle turbid solutions. It can be filtered through a 1-5 μ m filter membrane first, and then filtered through the corresponding filter membrane.

The screening process of microporous membrane belongs to precision filtration. Micro porous precision filtration refers to the filtration technology that filters out 0.1 μ m to 10 μ m particles. Generally, the filtration principle is divided into two types: surface type and deep type. Micropore filtration is a screening process and belongs to precision filtration. The filtering principle of the MF membrane produced by technology is surface filtration. Due to the fixed filtering aperture, the accuracy and reliability of the filtration can be guaranteed. Deep filtration is divided into non fixed irregular aperture and fixed irregular aperture. The former, such as synthetic fiber wound filter cartridges, is generally only used as a relatively rough pre filtration.

Its aperture is conical, and the smooth side with a smaller aperture is the front face; The rough side has a larger aperture than the reverse side. When installing, the front side (smooth side) should face up and the reverse side (dark side) should face down, otherwise it is easy for residue to block the aperture and interfere with the filtration rate. When the temperature is low, the solved filter membrane should be soaked in injection water at a temperature similar to the drug solution for 5-10 minutes to prevent cracking caused by a decrease in the tensile strength of the filter membrane due to temperature differences.
