Whatman Grade 589/3 ashless filter paper from Cytiva is particularly useful in capturing very fine particulate samples such as insoluble molecules in fats or oils or supporting ash free dry mass.

Supplier: Cytiva

Whatman Grade 589/2 filters from Cytiva are used in routine quantitative analyses, including analysis of aqueous suspension in paper, flour analysis, and sand content quantification.

Supplier: Cytiva

Whatman Grade 40 high-purity filters from Cytiva's business are general-purpose papers for quantitative analysis. Grade 40 filters are suitable for a variety of analytical filtration applications.

Supplier: Cytiva

Cytiva's Whatman Grade 42 quantitative papers have the finest retention of all Whatman ashless filter paper grades. Grade 42 is designed for gravimetric analysis and sample preparation for instrumental analysis.

Supplier: Cytiva

Cytiva's Whatman Grade 44 quantitative paper is a thin version of Grade 42 ashless paper. The thinness reduces the overall ash content, making Grade 44 well suited for analyses relying on ash-free dry weight.

Supplier: VWR International

Uses include filtration of aluminum phosphate, zinc ammonium phosphate, and silver chromate.

Supplier: VWR International

Useful for very fine precipitates such as barium and lead sulfates, stannic and nickel sulfides, and calcium hydroxide.

Supplier: VWR International

Use for retention of zirconium hydroxide, aluminum hydroxide, cobalt sulfide, and other coarse or gelatinous precipitates.

Supplier: Cytiva

With less than 0.01% ash, Cytiva's Whatman Grade 589/1 filter papers can be used for the Blaine test in the cement industry and as an ash content test filter for foodstuffs.

Supplier: Cytiva

Cytiva's Whatman Grade 41 environmental pollution papers are among the fastest filter papers in the Whatman ashless range. This gravimetric filter is well suited for quantitative analysis of soil and air.

Supplier: Cytiva

Whatman quantitative filters are designed for gravimetric analysis and the preparation of samples for instrumental analysis. They are available in three formats designed to meet your specific needs:

Supplier: AHLSTROM MUNKSJO FILTRATION LLC.

Ahlstrom Grade 74 is a medium flow rate ashless (Ash 0.007%) filter paper suitable for routine quantitative gravimetric techniques.

Supplier: AHLSTROM MUNKSJO FILTRATION LLC.

Quantitative filter papers are used for gravimetric analyses or filtrations where the precipitate is to be recovered.

Supplier: Cytiva

Cytiva's Whatman Grade 43 filters support inorganic analysis and other forms of instrumental analyses. The low ash content also makes Grade 43 appropriate for gravimetric analyses requiring sample combustion.

Supplier: Cytiva

Cytiva's Whatman Grade 542 filters are acid hardened to allow high retention of fine precipitates in applications such as metal determinations and hydroxide collection.

Supplier: Cytiva

Cytiva's Whatman Grade 541 acid hardened cellulose filter paper features high wet-strength, high chemical resistance, and a large nominal particle retention for fast analytical filtration.

Supplier: Cytiva

Whatman Grade 50 quantitative hardened low ash filter paper is highly glazed to enable recrystallization of very fine precipitates using Büchner funnel or Hirsch funnel filtration.

Supplier: Cytiva

Cytiva's Whatman Grade 52 is a general-purpose filter paper for quantitative analysis in Büchner funnel and other vacuum filtrations. The acid-hardened surface and low ash content enable efficient precipitate recovery.

Supplier: Cytiva

Whatman Grade 54 hardened low ash quantitative filter paper for Büchner funnel and Hirsch funnel filtration enables fast vacuum suction filtration for recrystallization applications.
