Cytiva's ready-to-use Whatman Grade GF/C glass microfiber filter papers offer a good flow rate and loading capacity that support total suspended solids analysis with a fine nominal particle retention of 1.2µm.

Glass microfiber filters for total suspended solids

Whatman binder-free glass microfiber filter grade GF/C from Cytiva is widely used as a total suspended solids filter for applications testing both potable water and waste water.

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 0.017mg/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. The barcode can be used to access a Cytiva certification of the filter weight from our website. Each box contains an additional box ID and barcode that can be used to download the weights of all 100 pans in that box.

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.
