Whatman Grade 40 ist äquivalent zu Schleicher &Schuell 589/2 und Munktell 389
Eigenschaften: -Mittelschnelle Filtration-Filtrationsgeschwindigkeit von 340 s/100 ml-Ein klassisches Allzweck-Filterpapier mit mittlerer Filtriergeschwindigkeit und mittlerem Rückhalt. Zu den typischen Anwendungen gehören z.B. gravimetrische Analysen für eine Vielzahl von Komponenten in Zement, Lehm, Eisen und Stahlprodukten
These are very pure filters suitable for a wide range of critical analytical filtration procedures. Whatman quantitative filters from GE Healthcare are designed for gravimetric analysis and the preparation of samples for instrumental analysis. They are available in three formats designed to meet specific needs. The classic general-purpose ashless filter paper with medium speed and retention. Typical applications include: gravimetric analysis for numerous components in cements, clays, iron, and steel products; as a primary filter for separating solid matter from aqueous extracts in general soil analysis; quantitative determination of sediments in milk; and as a pure analytical grade clean-up filter for solutions prior to atomic absorption (AA) spectrometry. Also used as a high-purity filter in the collection of trace elements and radionuclides from the atmosphere.
Grade 40: 8 µm
