Fine membrane prefilter benefits
Whatman Grade GF/D from GE Healthcare’s Life Sciences business is a membrane prefilter that provides protection for membranes with fine retention. The filter can be used with Whatman Grade GF/B filters to provide efficient membrane protection, especially during liquid scintillation counting.
Application Highly suitable for use in applications involving air filtration and for gravimetric analysis of volatile materials where ignition is involved. Because of the low resistance it is recommended for fluid flow and high particle loading capacity.
