Novel Membrane for Protein Precipitation Plates Introduced

Porex Corporation (“Porex”), a proven market leader in porous media solutions for the healthcare, industrial and consumer markets, has introduced POREX® PE Solvent Support Membrane, an innovative PE based solvent support media solution designed to retain low surface tension organic solvents for extended periods of time without plugging, leakage or breakthrough.

Used in applications like protein precipitation, high speed automation, protein purification, bio analytical analysis and drug discovery; the membrane helps retain acetonitrile and methanol for extended incubations without solvent leakage thus eliminating time-consuming centrifugation and transfer steps. Available in sheets or rolls. The POREX PE Solvent Support Membrane is chemically inert, hydrophobic, oleophobic, contains no leachables and is cost effective as compared to standard polytetrafluoroethylene (PTFE) membrane.

“Porex strives to create innovative solutions that solve the specific challenges of our healthcare and life science customers,” said William Midgette, President and Chief Executive Officer of Porex. “Porex scientists and engineers work hard to deliver industry-leading products that meet our customers’ needs and exceed their expectations.”

POREX PE Solvent Support Membranes for protein precipitation plates were tested for solvent leakage, nonspecific binding, flow rates and well blockage by an independent third party LC-MS/MS expert located in USA.
