VWR®, Qualitative Filter Papers
Product Details & Documents
These highly pure filter paper grades are produced from cellulose fibers with an alpha-cellulose content of nearly 100%, in accordance with precise quality standards. The ash content is approximately 0.06%.
Grade 402 and 302: General grade for qualitative tasks. Suitable for most sulphides. Determination of total fat content in dairy products.
Grade 403 and 313: Drugs, pharmaceuticals, liquors, tinctures, chromatography and protein-free filtrations in the clinical laboratory.
Grade 415 and 301: Coarse precipitates such as aluminium hydroxide, cobalt carbonate, mercury iodide, magnesium hydroxide and more.
Grade 417: Creped. Rapid filtrations where fine particle retention is not required.
Grade 307: For brewing industry. Embossed surface filter paper 70 g/m² for malt analysis in breweries (according to EBC standard).
Grade 600 and 310: Qualitative filter paper for use in routine laboratories, universities and hospitals. Made of 100% cellulose with no binder.
