Disposable non-sterile PTFE filtration media syringe filters feature Luer-Lok and pressure fitting. A tri-layer filter with glass microfiber and polypropylene prefilter raises absorption capacity and loading. 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.
