EZFlow® 13mm, 25mm, 47mm, and 90mm membrane disc filters are used to retain particles or microorganisms by surface capture. The membrane disc filters are available in Nylon or Hydrophobic PTFE with polypropylene support, in 0.2μm or 0.45μm pore sizes. The Nylon membrane has great chemical resistance, and is ideal for filtering more aggressive solutions such as alcohols and DMSO. The Hydrophobic PTFE membrane is bonded to a polypropylene support. 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.
