Allschoolabs Plain White PTFE Membrane Filters

Naturally hydrophobic, the PTFE membranes are made with polytetra-fluoroethylene laminated with a PP layer. Can be used in air and gas filtration or for chemically aggressive or acid samples. For the filtration of aqueous solutions, you should wet the membrane with isopropanol first. Available with 0.22?m or 0.45?m pore sizes. Compatibility Guide to?Membrane Filter Properties Identifying the filter material most suitable for your application based upon the nature of the liquid or gas you are filtering will ensure the best performance of your filter. Each membrane filter material has differing chemical and physical properties such as hydrophobicity, flow rate, extractables and protein retention making them suited to differing applications. Once you have selected the most compatible filter material, you will need to consider what pore size is most appropriate.
