Standard Qualitative Filter Papers are used for low gravity, or quadrant-folded applications. They have a higher level of α- cellulose than other filter papers. This means that they will weaken when the papers are introduced to water. We do not recommend Standard Qualitative Filter Papers if wet handling or vacuum work is necessary. In routine quadrant-folded applications the underlying strength of standard (untreated) grades does not present an issue.

Grade 301: is a very slow-filtering qualitative paper with high efficiency in retaining fine particles. It's commonly used in qualitative analytical techniques to identify materials in biological products, water and soil.

Application: Barium Sulphate, Metastannic Acid, Cuprous Oxide

Key Features

Qualitative Analysis: Ideal for determining and identifying materials in analytical procedures.

Biological Products: Used in the processing and analysis of biological substances.

Water and Soil Analysis: Effective in environmental testing to assess water and soil quality.

Fine Precipitate Filtration: Suitable for filtering fine precipitates like cold-precipitated barium sulfate.

Clarification: Used to clarify cloudy suspensions and wine, ensuring product clarity.
