Polyflow Membrane - SELECT cartridges deliver high-purity solvents and chemicals for semiconductor and microelectronic applications. The all-polypropylene construction is an excellent economic alternative to fluoropolymer- based cartridges for many chemicals, and provides highly efficient removal of particulate that could impact process quality.

Due to its innovative SELECT-Pleating, performance is increased markedly over similar competitive cartridges. Only one of every four pleats extends to the core, a feat that places most of the filtration area nearer to the outer diameter. This prevents crowding of the media around the core, which in standard-pleated cartridges tends to restrict the exiting flow. This innovative design results in higher flow rates, lower differential pressures, and longer life.
