This yields a non-sterile product and a low bubble point when integrity testing the filter after use. PES membrane is also extremely low protein binding minimizing the likelihood of target analyte binding. The membrane may be unstable. If there was no significant change in the bubble point, strength or appearance of the membrane, it was judged compatible with the chemical. *Chemical compatibility refers to the base membrane. Hydrophilic polyethersulfone has low protein adsorption and high drug compatibility. pes-membrane-compatibility, Find Quality pes-membrane-compatibility and Buy pes-membrane-compatibility from Reliable Global pes-membrane-compatibility Suppliers from … endstream endobj startxref Cellulose nitrate is compatible with some solvents that cellulose acetate is not. PES microfiltration membrane is specially designed for biochemical, inspection, pharmaceutical, and sterilization filtration devices. Therefore, the blood compatibility of the PES membranes can be further improved by the combination of appropriate hydrophilicity, anticoagulant PVP chains and anionic surface. The membrane or housing is basically unstable and is not recommended for use. Chemical Compatibility Chart.

Trial testing is recommended. The oleo-phobic PES membrane even resists wet-out with low surface tension fluids like oil or PES Membrane Processing. None of these published compatibility guides, for example, monitors the solvent’s ability to wet a membrane or increase extractables. 554 0 obj <>stream Supor polyethersulfone (PES) membrane has been optimized for biological, pharmaceutical, and sterilizing filtration requirements. The hydrophilic PES membrane wets out quickly and completely resulting in excellent flow rates and high throughputs. No significant change observed in flow rate or bubble point of the membrane, nor visible indication of chemical attack. Variations in temperature, concentrations, durations of exposure and other factors may affect the performance of the product. N = Not Recommended. PES powder is dissolved in an organic solvent—such as N-methyl pyrrolidone (NMP) in conjunction with polyvinylpyrrolidone (PVP)—and then it is spun into hollow fibers or cast into a membrane. Understanding these properties and taking a preventative—rather than reactive—approach towards filtration and membrane-sample compatibility, can minimize time spent troubleshooting and maximize filtration efficiency. h�b``�e``�e```4x̀ The membrane can be broadly utilized in sample preparation, sterile filtration and transfusion treatment. PES has both very low protein binding and extractables. The PES membrane can be blended with polymers possessing quaternary ammonium groups in an attempt to develop AEMs. If there was no significant change in the bubble point, strength or appearance of the membrane, it was judged compatible with the chemical. Usually the membrane or seal between the membrane and filter shell are compromised when the filter materials aren’t chemically compatible with the filter solution. 1) gamma irradiation feasible for Minisart ® Air Chemical Compatibility Chart For Minisart® Syringe Filters Chemical Compatibility Tool The main purpose of the chemical compatibility tool is to determine the resistance of in-house materials to certain chemicals.
