The quantitative filter is specially designed for the preparation of gravimetric analysis and instrumental analysis samples. They are available in three formats, designed to meet your specific needs.
Ashless: Suitable for various key analysis and filtering procedures.
Hardened low ash content: Especially suitable for Büchner filtration, where the tough and smooth surface of the filter makes it easy to recover sediment.
Hardened and ash-free: The tough surface makes these filters suitable for a wide range of critical filtration procedures.
Grade 40: 8 μm (medium flow filter paper)
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 AA spectrometry.
