General purpose, high efficiency filter. Widely used in biochemistry for filtration of precipitated proteins. An ideal filter for radioimmunoassay of weak beta emitters by scintillation counting where Grade GF/A permits very high efficiencies. A standard for air pollution monitoring, e.g., collection of oil mists and polycyclic hydrocarbons. Flow rate: Fast. Retention 1.6 µm. 100 per Pkg.
