Whatman™ Grade 50 Quantitative Filter Paper Available on GSA/VA Contract for Federal Government customers only.

Enables strong retention for very fine crystalline precipitates. Whatman™ Grade 50 Quantitative Filter Paper withstands shredding, wet handling, and precipitate removal by scraping.

Whatman™ Grade 41 Quantitative Filter Paper Available on GSA/VA Contract for Federal Government customers only.

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

Whatman™ Whatman™ Quantitative Grade Papers

Used for critical analytical filtrations. GE Healthcare Whatman™ Quantitative Grade Papers  are acid hardened, which reduces ash to an extremely low level.

Whatman™ Grade 43 Quantitative Filter Paper Available on GSA/VA Contract for Federal Government customers only.

Contains very low ash content appropriate for gravimetric analyses requiring sample combustion. Whatman™ Grade 43 Quantitative Filter Paper can be ashed during gravimetric analysis without contributing substantially to the measured weight.

Whatman™ Grade 44 Quantitative Filter Paper Available on GSA/VA Contract for Federal Government customers only.

Reduces overall ash content and the amount of time required for filtration. Whatman™ Grade 44 Quantitative Filter Paper provides faster gravimetric analysis with filter thinner material.

Whatman™ Quantitative Filter Papers - Grade 41 Available on GSA/VA Contract for Federal Government customers only.

Contains extremely low ash content at 0.007%. Whatman™ Quantitative Filter Papers – Grade 41 aid analytical procedures involving coarse particles or gelatinous precipitates.

Whatman™ Grade 40 Quantitative Filter Paper Available on GSA/VA Contract for Federal Government customers only.

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

Whatman™ Quantitative Filter Papers - Grade 40 Available on GSA/VA Contract for Federal Government customers only.

Separates solid matter from aqueous extracts in soil analysis and collects atmospheric trace elements and radionuclides. Whatman™ Quantitative Filter Papers – Grade 40 also filter numerous components in cements, clays, iron, and steel products.

Whatman™ Grade 589/2 Quantitative Filter Paper Available on GSA/VA Contract for Federal Government customers only.

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™ 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™ Grade 42 Quantitative Filter Paper Available on GSA/VA Contract for Federal Government customers only.

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

Whatman™ Grade 52 Quantitative Filter Paper

Enables efficient precipitate recovery with acid-hardened surface and low ash content. Whatman™ Grade 52 Quantitative Filter Paper prevents fiber shredding during vacuum filtration or precipitate collection.

Whatman™ Grade 589/1 Quantitative Filter Paper Circles Available on GSA/VA Contract for Federal Government customers only.

Filters course precipitates using material with virtually no ash content. Whatman™ Grade 589/1 Quantitatve FIlter Paper Circles support cement fineness measurement or determination of the ash content in foodstuffs.
