Qualitative Filter Paper is available in three standard grades.

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

Medium fast cellulose filter paper with high wet strength. This paper has the same chemical resistance characteristics as Grade 1573.

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

A dense prepleated filter paper for collecting very small particles and removing fine precipitates.

Supplier: Cytiva

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

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

These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.

Supplier: Cytiva

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

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

Grade 3645 papers are suitable for testing seeds with small white rootlets.

Supplier: Cytiva

A general qualitative filter with creped surface. Widely used in industrial laboratories and students laboratories for routine filtration.

Supplier: Cytiva

Standard Whatman grade filter paper for a variety of routine applications in food and beverage industries. Well-suited for determination of fat content in food or removal of carbon dioxide and turbidity from beverages such as beer.
