47mm, and 90mm membrane disc filters are used to retain particles or microorganisms by surface capture. The membrane disc filters are available in a nylon material or hydrophobic PTFE material with polypropylene support, offered in 0.45 m or 0.45 m pore sizes. The Nylon membrane is has great chemical resistance and makes them ideal for filtering more aggressive solutions such as alcohols and DMSO. The Hydrophobic PTFE membrane is bonded to a polypropylene support and due to its extreme chemical compatibility, they are ideal for the filtration of solvents and acids or other aggressive chemicals. All materials comply with USP Class VI Standards and FDA compliances.
