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 41: 20 μm (fast filter paper)
The fastest ashless filter paper, recommended for analytical procedures involving coarse particles or gelatinous precipitates (e.g., iron or aluminum hydroxides). Also used in quantitative air pollution analysis as a paper tape for impregnation when determining gaseous compounds at high flow rates.
