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 589/1 ½ : 12-25 μm (fast filter paper)
The established standard in quantitative analysis for the filtration of coarse precipitates. Ashless filter paper with very high flow rate. Used for many quantitative standard methods, especially for gravimetric applications (e.g., determination of the ash content in foodstuffs), or for the Blaine test in the cement industry.
