Suitable for filtration of aluminum phosphate, barium carbonate, lead chromate, and more.

Grade 410 filter paper is useful in analytical operations involving filtration of cuprous oxide, lead sulfate, barium sulfate, manganese carbonate, and more.

Good for rapid filtrations where fine particle retention is not required.

Good for coarse precipitates such as aluminum hydroxide, cobalt carbonate, mercury iodide, magnesium hydroxide, and more.

Used for drugs, pharmaceuticals, liquors, tinctures, chromatography, and protein-free filtrations in the clinical laboratory.

Crepe fluted circles are ideal for gelatinous and coarse precipitates.

Owing to their extremely high purity our seed testing papers provide reliable and reproducible results. The papers are made from pure cellulose without any additives and do not contain any substances that could influence the growth of the seeds. The constant water absorption of the papers ensures the continuous provision of the required amount of water.

A more retentive and absorbent media than CFP1, with approximately 8 µm and a medium to slow flow rate.

The fastest flow rate demonstrated by any of the qualitative cellulose filter medias, resulting in a low retention rate of approximately 25 µm.

Very widely used filter media demonstrating retention of approximately 11 µm and medium flow rate.

Very similar basis and thickness to CFP5, but with a slightly less retentive porosity.

Filtration of very fine particulate and clarification with applications in environmental sciences and chemical analysis.

Whatman Grade 5V fine particle filter retains particles as small as 2,5 µm for qualitative analysis

Whatman Grade 1V lab filter paper from Cytiva business is a widely used pre-folded filter for many general filtration applications.

Virtually identical to CFP1, but twice as thick, resulting in a significantly slower flow rate with a retention of approximately 6 µm.

A thick filter paper with high loading capacity. Combines medium retention with medium-fast to fast filtration speed.

Cone folded filter paper saves valuable time when undertaking repetitive or multiple analyses.

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.

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.

These cellulose filters are used in qualitative analytical techniques to determine and identify materials. A standard grade filter paper for fine precipitates.

These are cellulose qualitative filter papers with low fat content.

Grade 604½ Qualitative Filter Papers for coarse precipitates. Maintains flow rate due to the reduction in filter paper contact with funnel side and the self-supporting shape of the filter itself.

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

Pack of 100 premium Qualitative Filter Papers with medium speed (85 gsm) and 10 µm pore size.

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

Whatman Grade 4V filter paper is well suited for qualitative analysis or general filtration of coarse particles. The fluted filter design increases filtration speed, flow rate, and loading capacity.

A standard grade filter for boiler water analysis.

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

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

These cellulose filter papers are intermediate in speed and retention between grades 1 and 4.
