Qualitative analytical filter paper

The qualitative analytical filter papers from the AllFilter range by AllChimie are designed for routine filtrations and qualitative analyses where weighing of the residue is not required. Manufactured from high-purity cellulose, they cover essential solid/liquid separation needs in the laboratory.

These qualitative papers feature a broad range of porosities and filtration speeds: fast papers for high flow filtrations, medium papers for clarification, slow papers for fine precipitate retention. They match the equivalent international grades commonly used in analytical protocols.

Available in round or pleated versions, they fit standard laboratory funnel diameters. Typical applications cover food analysis, environmental monitoring (soils, water), sample preparation and clarification of coloured or loaded solutions.

For efficient gravity filtration, place the paper in a glass funnel (or plastic funnel to avoid breakage), mounted on a laboratory support above a receiving beaker. For analyses requiring precise residue weighing, consider the low-ash quantitative analytical filter papers.
