Whatman™ Grade 43 Quantitative Filter Paper

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™ Reeve Angel 230 Creped Qualitative Circles

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

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™ Hardened Ashless Quantitative Filter Paper Grade 989 Circle

Recommended for quantitative analysis, gravimetric analysis, chromatography and electrophoretic work

Whatman™ Quantitative Filter Paper: Grade 42 Sheets

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

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 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 2V Folded Qualitative Filter Papers

Saves time required to fit circles into conical funnels. Whatman™ Grade 2V Folded Qualitative Filter Papers provide medium flow and nominal particle retention rating of 8µm at a higher filtration speed.

Whatman™ Quantitative Filter Paper: Grade 50 Circles

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