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™ Grade 52 Quantitative Filter Paper Available on GSA/VA Contract for Federal Government customers only.

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™ Quantitative Filter Paper: Grade 540 Circles Available on GSA/VA Contract for Federal Government customers only.

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.

Labconco™ Fast-Freeze™ Flask Filter Paper

Fits into top of flask to prevent partial loss of product during freeze drying.

Whatman™ Environmental pollution analysis papers with gravimetric filter suited for quantitative analysis of soil and air. Available on GSA/VA Contract for Federal Government customers only.

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

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™ Quantitative Filter Paper: Grade 40 Circles: PROMO

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™ 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.
