Pre-washed, dried or ignited, cooled and weighed Glass Microfibre filters, which eliminate 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. Each ready-to-use filter is placed in an individually barcoded aluminum pan that notes the filter weight. The barcode can be used to access a GE 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.
Solids: For suspended and dissolved solids. Pre-washed, dried, cooled, and weighed filters with certified mass loss between washing and drying steps of the lesser of less than 0.5 mg or 4% in accordance with US EPA Lab Standard Method 2540 parts C and D. Solids, double weigh: As Solids additionally the drying, cooling and weighing steps are repeated twice for highest regulatory concerns. Volatiles: For volatile substances. Pre-weighed. Aligned to US EPA Laboratory Standard Method 2540 parts C, D, and E Volatiles, ignited: As Volatiles but pre-washed and pre-fired at 550 °C instead of pre-weighed.
Applications: To be used for solid analysis as well as a wastewater filter for a wide range of water monitorings.
