50PCS Hydrophilic Glass Fiber Microporous Filter Membrane for Particulate Matter Sampling - 0.22μm-5μm(0.00022x80mm)

The glass fiber membrane is made of borosilicate glass fibers and has a capillary fiber structure. It can adsorb more water than the same type of fiber filter paper, has a fast flow rate, a large pollutant capacity, a high load-bearing capacity, can withstand high temperatures, and can effectively retain fine particles. This glass fiber membrane is hydrophilic in nature and is suitable for pre-filtering of water samples, filtration of ink, cell solutions, electrolytes, HPLC solutions, etc. Notes for Attention Different sizes of filters have specific requirements for the diameter of the pre-filter membrane. If the diameter is too large, the edges will extend below the sealing ring, causing liquid leakage. When filtering viscous and difficult-to-filter liquids, a multi-layer filtration method is usually adopted. Two to three layers of different pore size filter membranes are stacked, and a polyester partition layer is added between the filter membranes to facilitate liquid filtration. A glass fiber pre-filter membrane is added on the top layer. ·The texture of the glass fiber filter membrane is relatively loose and soft, and its strength is not very good. It is prone to breakage when bent. When using it, try to avoid touching sharp objects. When filtering some organic solvents, the filter membrane may become "paste-like".
