Supplier: Cytiva

A prepleated filter used for many routine analytical applications in different industries (e.g., particle separation from food extracts or filtration of solids from digested environmental samples, e.g., for ICP/AAS analysis).

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

A standard grade filter esed in sample preparation, e.g., in the beverage industry for residual sugar determination, acidic spectra, refractometric analysis, and HPLC.

Supplier: Cytiva

Whatman Grade 1 Qualitative Filter Papers are the most widely used filter paper for routine laboratory applications, qualitative analytical separations, and clarifying liquids. They are the standard grade cellulose filter papers for medium flow rates.

Supplier: Cytiva

Whatman Grade 4 Qualitative Filter Papers are a standard grade, high flow rate filter paper. They are useful in qualitative analytical separations when fast flow is required and the collection of fine particles is not critical.

Supplier: Cytiva

Whatman Grade 114V smooth filter paper from Cytiva is wet-strengthened for high mechanical stability. Grade 114V fluted filters are suitable for recovery of large particles and gelatinous precipitates.

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 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

A prepleated filter for use with a conical filter funnel, offers fast filtration and high loading capacity for analysis involving coarse particles 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 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

A standard grade filter for boiler water analysis.

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 113V creped filter paper, for use with a conical filter funnel, offers fast filtration and high loading capacity for analysis involving coarse particles or gelatinous precipitates.

Supplier: Cytiva

Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses.

Supplier: Cytiva

Ultra high loading capacity with a particle retention well suited for use with coarse or gelatinous precipitates.

Supplier: Cytiva

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

These extremely strong filter papers have a high wet strength due to the addition of a small quantity of chemically stable resin. Normal qualitative applications will not introduce any significant impurities into the filtrate. The resins do, however, contain nitrogen so these grades should not be used in Kjeldahl estimations.

Supplier: Cytiva

These filter papers can be used for the absorption of culture media, as a blotting paper, for electrophoresis and amino acid chromatography.
