Disposable non-sterile PES / Polyethersulfone hydrophilic filtration media syringe filters feature Luer-Lok and pressure fitting. High filtration flow rates and an inherently low affinity for proteins. Low extractables. Use for introduction of additives into tissue culture vessel. Certified for Ion Chromatography. Use for final filtration of bacteriophage and infusion solutions and tissue culture, proteins, buffer and nucleic acids filtration. Ideal for applications requiring maximum sample recovery. Use to filter hybridization solutions and probe to reduce backgrounds. Food, beverages and ultra pure water final filtration. Filters are ultrasonically bonded for reliability and the filter media type is clearly inscribed on barrel. Excellent unit-to-unit and lot-to-lot reproducibility and consistency. The unique concentric funnel shaped barrel increases volume and decreases back pressure.
