Grade GF/C is pre-rinsed and dried, grade GF/C RTU is additionally pre-treated with washing, drying, cooling (in a desiccator) and weighing steps, aligned to the requirements of EN 872. It is certified that these filters have weight loss of less than 0.017 mg/cm2 after preparation, which is required by the standard. Each grade GF/C RTU ready-to-use filter is placed in an individually barcoded aluminum pan that notes the filter weight. Each box contains an additional box ID and barcode that can be used to download the weights of all 100 pans in that box.
Applications: For cell harvesting, liquid scintillation counting and binding assays, especially suitable for use in applications involving air filtration and for gravimetric analysis of volatile materials where ignition is involved.
