Fine Chemicals Elements Utilize Thin-Film Composite Membrane

Fluid Systems SPIRAPRO TFC line of SR3 and RO pharmaceutical and fine chemicals spiral elements utilizes a proprietary, polyamide, thin-film composite membrane with a sanitary spiral-wound net outer-wrap. The molecular weight cut-off for the TFC SR3 allows the membrane to pass monovalent salts while providing high retention of multivalent ions and uncharged organic solutes. These elements are useful for separating small molecules from chromatography effluent or other intermediate purification processes. TFC RO reverse osmosis elements are suited for concentrating compounds with a molecular weight of 100 to 2000 daltons. By providing high rejection at low pressure, they increase efficiency and reduce costs.
