Filter Paper

Covers a wide range of laboratory applications and is frequently used for clarifying liquids. Whatman™ Qualitative Filter Paper: Grade 1 Circles are widely used standard grade filter papers for routine applications with medium retention and flow rates.

Filters and retains extremely small particles. Whatman™ Quantitative Filter Paper: Grade 42 Circles are suitable for processes that require ashing.

Used for high precipitate capacity and increased wet strength. Whatman™ Qualitative Grade Plain Circles and Sheets - Grade 3 provide double the thickness of Whatman Grade 1.

Strengthened with chemically stable resin additive. Whatman™ Grade 113 Wet-Strengthened Qualitative Filter Paper Circles boast the fastest flow rate of the qualitative grades. Creped surface promotes ultra high loading capacity.

Enables high retention of fine particles in chemically harsh conditions. Whatman™ Quantitative Filter Papers: Grade 542 Circles are well suited for use in capturing fine precipitates in applications such as metal determinations and hydroxide collection.

Offers a high degree of internal surface area for greater adsorption of product
