Whatman® GF/D Glass microfiber filters

Whatman® GF/D Glass Microfiber filters are considerably faster in flow rate and overall filtration speed than cellulose filter papers of similar particle retention. The filter is thick and consequently exhibits a high loading capacity. Designed as a membrane prefilter and available in sizes to fit most holders. GF/D will provide good protection for finely retentive membranes. It can be used in combination with GF/B to provide very efficient graded prefilter protection for membranes.

Whatman® GF/D Glass Microfiber filters have a particle retention size of 2.7 μm at 98% efficiency.
