Hahnemühle Quantitative Filter Paper Circles Pack of 100 Grade 589/3 1 2 Micron Particle Retention Slow Flow Speed Fine Filtration Quality Round Cellulose Discs Lab Supplies 125 mm Diameter

GRADE 589/3 FILTRATION: Hahnemühle 125 mm ashless and blue ribbon filters (approx. 0.004%) are designed for quantitative analysis, routine gravimetric tests and sample preparation for instrumental analysis. SLOW FLOW RATE: Quantitative filter paper with 1–2 μm pore size has a slow flow rate that makes it suitable for capturing very small particles while maintaining highest filtration efficiency. CELLULOSE DISCS: Our quantitative filter circles are composed of highly pure super-refined cotton linters and α-cellulose with a content of above 95%, which provides the filter paper with high stability and durability. NEUTRALISED: These filter papers are acid-washed and rinsed with water to neutralize any acidic substances present, resulting in a filter paper that is free of minerals and metallic ions. This makes it ideal for the detection of metallic ions. APPLICATIONS: Quantitative filter papers discs are suitable for use in food and beverage, agriculture, environmental analysis, chemicals, oil refinery, and pharmaceuticals. Especially suitable for quantitative analysis, Büchner funnels, pressure or vacuum filtration.
