Filter paper, qualitative

Circles. Qualitative. Thin and very strong. Smooth surface.

Circles. Prepleated. Qualitative. Thin and very strong. Smooth surface.

Circles. Quantitative. Hardened. Ashless. Highly retentive for fine precipitates.

Circles. Qualitative. Slow, faster as Grade 5. Supplied in packs of circles as outlined below.

Very smooth surface, very strong, with enhanced wet strength. Chemically stable against acids and weak alkalis, especially suited to vacuum and pressure filtration.

Highly pure filter paper (approx. 0.08% ash) recommended for precise identification of materials and for sample preparation prior to sensitive detection methods. These filter papers are perfectly qualified for food control according to LFBG paragraph 64 para. 1 and 2, beverage analysis and environmental monitoring.

• Made of the same raw materials (super-refined cotton linters and cellulose) like quantitative filter papers
• High stability and durability due to alpha-Cellulose content above 95%

Fast, grained.

For carrying out germ resistance tests. All papers are made from high-purity cellulose and are free of spores, bacteria and toxic substances that could influence the germination of the seeds. The highly absorbent papers store water for the entire duration of the tests. All germ test papers meet the requirements of ISTA and AOSA.

• Reliable seed testing
• Conductivity 40 mS/m
• pH value between 6.0 and 7.5
• High absorbance
• Roots do not grow through the paper
• Papers conform to ISTA recommendations of 2017

GB 003, GB 005. High purity. Very absorbent. Easy to use. Suitable for all protein and nucleic acid blotting techniques.
