Filtration aids

Can be used up to a maximum of 200 °C. With organic binder.

This binder free paper offers fine particle retention, high flow rate and good loading capacity. it is used for high efficiency laboratory filtration as well as air sampling. This filter is stable up to +500 °C.

Can be used up to a maximum of 500 °C. Without binders.

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.

To be used for solid analysis as well as a wastewater filter for a wide range of water monitorings.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. Each box contains an additional box ID and barcode that can be used to download the weights of all 100 pans in that box.For volatile substances. Pre-weighed. Aligned to US EPA Laboratory Standard Method 2540 parts C, D, and E.

White, without binder. The filters can be heated up to 500 °C and retain their structual stability without weight loss. For determining volatile suspended solids in wastewater.HydrophilAutoclavable

These glass microfiber filters are made from borosilicate glass and strengthened with an organic binder to provide high mechanical stability.Temperature resistance up to 180 °CMedium filtration speedCan be used as a roll filter in automated applications

Glass microfibre filters have a fast filtration and a high loading capacity and particle retention rate. Manufactured without chemical binder from high grade borosilicate glass. (Exception: GF6, GF9). They are suitable for gravity or low suction filtration. Filtration speeds generally very much higher than conventional cellulose papers. Efficient retention of micron size particles. Must be used flat. Ideal for use in flat perforated plate Buchner type funnels (not sintered glass models). Can be used up to 500 °C.Manufactured from quartz microfibre to withstand high temperatures. Can be used up to 500 °C.

White, without binder. The filters can be heated up to 500 °C and retain their structual stability without weight loss. For filtering fine precipitates such as protein, nucleic acids and serum precipitates.HydrophilAutoclavable
