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 595½ Pleated Circles

Pleated to save time and achieve optimal fit in conical filter funnels. Whatman™ Qualitative Filter Paper: Grade 595½ Pleated Circles provide extra surface area to increase total loading capacity.

Whatman™ Quantitative Filter Paper: Grade 589/1 Circles

Designed for fast filtration of coarse precipitate. Whatman™ Grade 589/1 Quantitatve FIlter Paper Circles support tests such as cement fineness measurement in a standard Blaine test or determination of the ash content in foodstuffs. 

Whatman™ Quartz Air Sampling Filters, Grade QM-A, Circle

Used in many air sampling filter applications, including sampling of acidic gases, stacks, flues, and aerosols. Whatman™ Quartz Air Sampling Filters are sequentially numbered according to U.S. Environmental Protection Agency (EPA) standards and are suitable for most applications.

Whatman™ Grade 54 Quantitative Filter Paper

Supports collection of coarse and gelatinous precipitates with minimal fiber shredding, even when wet. Whatman™ Grade 54 Quantitative Filter Paper has a hard, smooth surface to sustain vacuum and suction filtration.

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™ 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 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™ Grade 589/2 Quantitative Filter Paper

Retains medium fine precipitates using material with virtually no ash content. Whatman™ Grade 589/2 Quantitative Filter Paper is used when medium fine precipitates are being collected and papers must be ashed to support analysis.

Whatman™ Shark Skin Filter Paper

High wet strength allows use under pressure

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.

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.
