Glass Microfiber Papers Offer Faster Filtering of Difficult Solutions—Without Clogging!
Use Whatman Glass Microfiber GS Filter Papers when flow rate is high and loading capacity is heavy. Leaves cellulose filters far behind. Each filtration takes less time, and a single filter handles larger volumes. Smaller-sized filters let you use smaller equipment.
For high-efficiency, general purpose laboratory filtration, choose Grade GF/A (1.6µm). Choose from three sizes. Pkgs. of 100.
Grade 934-AH (1.5µm) is often used in water pollution monitoring for suspended solids. Like all glass microfiber filters, load capacity is high with high retention efficiency at high flow rates. Choose from seven sizes. Pkgs. of 100. Whatman products are intended for research and development purposes only.
