Whatman™ Grade 113 Qualitative Filter Papers

High loading capacity with a particle retention suited for use with coarse or gelatinous precipitates.

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™ Environmental pollution analysis papers with gravimetric filter suited for quantitative analysis of soil and air.

Environmental pollution analysis papers with gravimetric filter suited for quantitative analysis of soil and air.

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™ 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™ Quantitative Filter Paper: Grade 41 Circles

Use for quantitative air pollution analysis as a paper tape for impregnation when determining gaseous compounds at high flow rates or for quantitative air pollution analysis. Whatman™ Quantitative Filter Paper: Grade 41 Circles are commonly used in preparing samples for metal analysis after nitric acid digestion.

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™ Whatman™ Qualitative Grade Plain Circles and Sheets - Grade 3

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.

Whatman™ Reeve Angel 230 Creped Qualitative Circles

Provide reliable performance for non-critical industrial laboratory and student lab applications

Whatman™ Grade 0905 Qualitative Creped Filter Paper Sheets

Designed for applications ranging from the filtration of beverages to the purification of electroplating baths

Folded filter paper saves time, increases loading capacity

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™ Cellulose Nitrate Membrane Filters

Manufactured under strictly controlled conditions. Whatman™ Cellulose Nitrate Membrane Filters have a noticeably improved flexibility and are made to tolerate abuse during handling, loading, and autoclaving without sacrificing integrity.

Whatman™ Grade QM-A Microfiber Filter

High-purity quartz filters for air sampling filter applications.

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 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.
