[PTFE] Polytetra-fluorethylene membranes
 MF-PT
Naturally hydrophobic, the PTFE membranes are made with polytetra-fluroethylene laminated with a PP layer. They can be used in air and gas filtration or for chemically aggressive or acid for samples. For the filtration of aqueous solutions, you should wet them first with isopropanol.
