Whatman Grade GF/D Glass Microfiber Filters are thick and offer good loading capacity. GF/D can also function as a prefilter when used with GF/B, and it comes in many sizes to fit most filter holders.
- Thick filter media for increased loading capacity
- Nominal particle retention of 2.7 µm
- Can be used as a fine membrane prefilter
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.
