Whatman Filter Paper Grade GF/C RTU Microfiber Glass Filter, Binder Free, Ready to Use

The GF/C RTU line, part of the Whatman GF/C filter paper family, is pre-treated with washing, drying, cooling (in a desiccator), and weighing steps aligned to the requirements of EN 872—the European norm for testing suspended solids in water. The Cytiva quality organization certifies that these filter paper have weight loss of less than 0.017 mg/cm2 after preparation, as required by the standard. Each ready-to-use glass filter paper is placed in an individually barcoded aluminium pan that notes the filter paper weight.

Available in a range of sizes, GF/C grade microfiber filters are widely used for cell harvesting, liquid scintillation counting, and binding assays where more loading capacity is required. They are highly suitable for use in applications involving air filtration and for gravimetric analysis of volatile materials where ignition is involved. GF/C grade RTU microfiber filters can be used for dissolved and suspended solids and are available in packs of 100.
