Membrane, Hydrophobic PTFE, Pore: 0.45μm, Dia: 13mm, 400pcs/pk

The microporous membrane filter is mainly used for the filtration of mobile phase and samples during the chromatographic analysis, especially for preventing chromatographic column and infusion pump line system and sample valve from pollution.
Given the separation characteristics of microporous filter membranes, their primary application is to retain particles, bacteria, and other pollutants from liquid phases, achieving purification, separation, and concentration objectives. In the context of microfiltration, the retention properties of the membrane are characterized by its pore size, typically ranging from 0.1 to 1 μm, enabling the separation of large-diameter entities such as bacteria and suspended solids.
