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 42: 2.5 μm (slow filter paper)
A world standard for critical gravimetric analysis with the finest particle retention of all cellulose filter papers. Typical analytical precipitates include barium sulfate, metastannic acid, and finely precipitated calcium carbonate.
