Syringe Filters and Discs

NanoCeram® Electropositive Syringe Filters are specifically designed to combine high throughputs and maximum sample recovery when filtering or sterilizing viscous proteineceous solutions. The media has a high capacity for particles as large as tens of microns or as small as a few nanometers. It is well suited for maximum sample recovery such as tissue culture media preparation, sterile or non-sterile filtration and clarification of biological fluids, protein and enzyme filtrations, hybridization buffers, and other aqueous solutions.
NanoCeram® alumina fibers attract and retain virus and other macromolecules by electrostatic forces.  These fibers have been incorporated into fibrous ("depth") filters and have found to have ~ 6-7 logs of virus retention even at flow rates several orders of magnitude greater than could be obtained using ultraporous membranes. A single layer of media retains greater than 99% of 30 nanometer monodisperse latex spheres or 25 nm virus, giving it an Absolute rating of 0.03 microns.   While Absolute 0.2 µ membranes are transparent to virus, 3 layers of NanoCeram® retain greater than 99.9999%.  Yet flow rates are hundreds of times greater than such membranes. The NanoCeram® filter is effective over pH 5-10, water temperatures of 4 to 50 degrees C and in the presence of dissolved salts.
Features and Benefits: Rapidly adsorbs particles, no matter how small. NanoCeram® filter is effective over pH 5-10, water temperatures of 4 to 50 degrees C and in the presence of dissolved salts. Flow rates are hundreds of times greater than membranes. Ideal for applications requiring maximum sample recovery Connections: Female LuerLok inlet,
