Whatman™ Quantitative Filter Paper: Grade 541 Circles

Recommended when fast filtration of a gelatinous precipitate for gravimetric analysis is performed on a strongly acidic or alkali solution. Whatman™ Quantitative Filter Paper: Grade 541 Circles  are acid hardened cellulose filters, which reduces ash to an extremely low level.

Whatman™ Grade QM-A Microfiber Filter

High-purity quartz filters for air sampling filter applications.

Whatman™ Qualitative Filter Paper: Grade 2 Circles

Retains and absorbs more than Grade 1 filters, with a corresponding increase in filtration time. Whatman™ Qualitative Filter Paper: Grade 2 Circles are used for monitoring specific contaminants in the atmosphere and in soil testing.

Whatman™ Quantitative Filter Papers: Grade 542 Circles

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.

Whatman™ Grade 589/3 Quantitative Filter Paper Circles

Captures very fine particulate samples such as insoluble molecules in fats or oils. Whatman™ Grade 589/3 Quantitative Filter Paper Circles provide accurate measurement of ash-free dry mass.

Whatman™ Qualitative Filter Paper: Grade 1 Circles

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.

Whatman™ Reeve Angel 201 Smooth Qualitative Filter Paper: Circles

For routine, noncritical laboratory filtration applications

Whatman™ Glass Microfiber Filter Paper Grade 6

Captures tiny particles without becoming weak. Whatman™ Glass Microfiber Filter Paper Grade 6 may also be used for determination of filterable substances and residue upon ignition or analysis of aggressive media.

Whatman™ Quantitative Filter Paper: Grade 40 Circles

Supports accurate analysis in applications sensitive to very low levels of background contamination. Whatman™ Quantitative Filter Paper: Grade 40 Circles are additionally useful in gravimetric analysis where ash content might affect weight measurements of combusted samples.

Whatman™ Qualitative Filter Paper: Grade 4 Circles

Filters and retains course particles for monitoring air pollution. Whatman™ Qualitative Filter Paper: Grade 4 Circles are used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical.

Whatman™ Quantitative Filter Paper: Grade 42 Circles

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

Whatman™ Grade 91 Wet Strengthened Qualitative Filter Papers - Sheets

High wet strength due to the addition of chemically stable resin

Whatman™ Quantitative Filter Paper: Grade 540 Circles

Use as a gravimetric filter during analysis of metals in acidic or alkaline solutions and in the collection of hydroxides. Whatman™ Quantitative Filter Paper: Grade 540 Circles acid-treated surface prevents tearing during filtration and allows the user to scrape precipitates from the paper.

Whatman™ Qualitative Filter Papers: Grade 4 Sheets

Filters and retains course particles for monitoring air pollution. Whatman™ Qualitative Filter Papers: Grade 4 Sheets are used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical.
