Description
These ready-to-use (RTU), Grade 934-AH RTU Cytivas Whatman™ Glass Microfiber Filter Papers are the time-saving version of Cytivas 934-AH glass microfiber filter papers, which are widely used for total suspended solids analysis. Cytivas Whatman™ glass microfiber filter papers in grade 934-AH RTU have been pre-washed, dried (or ignited), cooled, desiccated and weighed, which eliminates the pre-treating steps that are otherwise required by the US EPA Laboratory Standard Method 2540 parts C, D, and E. These glass microfiber filter papers also have fine particle retention of 1.5 µm at high flow rates to process heavy, turbid samples. In addition, the pre-weighed glass microfiber filter papers are packaged with a barcoded aluminum pan noting the filter weight. The barcode from this pan can be used to find documentation of the filter weight on the Cytiva website. Each box of 934-AH RTU filters also has a barcode that can be used to download the weights of all filters from that box.
