网页2022/06/28 · It is a hydrophilic filter membrane with consistent high flow rate characteristics, and can provide consistent pore structure and wide pore size specifications. The filter membrane is designed with grid lines to facilitate the calculation of colony counts and is suitable for the detection of bacterial counts, coliforms and other microorganisms.
网页In addition, filter holders allow the retrieval of the filter material for particulate examination. Filter holders in plastic, aluminum and stainless steel may range in size from 13 mm to 293 mm - categorized by the size filter they can accommodate. We offer a variety of options including syringe filters, in-line filters and filter funnels.
网页If the membrane does not have a substrate, it is bio-directional and either side can be used as the inlet. If it has a substrate, the substrate layer will be more coarse and ridged than the membrane side. The membrane side would be the inlet and the coarse substrate side the outlet. The solvent should enter the inlet side of the membrane first.

网页Membrane filters are either hydrophobic or hydrophilic. The rate of flow through a filter is affected by the resistance of the filter, the viscosity of the solution, and pressure. Filters are commonly composed of mixed esters of cellulose, polysulfone, polyvinylidene difluoride, nylon 66, polycarbonate, or polytetrafluoroethylene.
