Evaluating the performance of polysulfone membrane filters in SC-1 chemistries
of the chemically resistant polysulfone membrane maximizes flow capability and allows for a double-layer filter configuration that enhances particle capture at a lower flow resistance than is possible with conventional single-layer PTFE filters. The membrane material is offered in 2.6-in.-OD (1.08-in

is polytetrafluoroethylene (otherwise known as PTFE or Teflon). Photo provided by Pall Corp. (East Hills, NY) Filters were once thought of as a sheet with holes in it, like a kitchen colander. However, scanning electron micrographs demonstrate that membrane filter structures are more like very thin sponges

In-Process Filtration of Solvent Strippers Advanced solvent resist-stripping processes present challenges to in-process filtration, involving particle loading, flow rate, viscosity, and chemical compatibility. Filters constructed of Teflon polytetrafluoroethylene (PTFE) and perfluoroalkoxyl
