Quantitative Filter Papers Used in Gravimetric Analysis

Which filter paper is used in gravimetric analysis? Quantitative filter papers are your ideal choice. Hawach quantitative filter papers ash content is less than 0.007%, and its impurity dissolution rate is very low. Quantitative filter paper is suitable for a wide range of critical gravimetric analytical filtration procedures.

Hawach filter paper used in gravimetric analysis is particularly suited for quantitative routine analysis. The ashless filter paper is made from pure alpha cotton cellulose and double acid washed then rinsed with ultra-pure water to neutralize and good for gravimetric analysis and preparation of samples for instrumental analysis. Quantitative filter papers are manufactured under intense quality control standards to be of the highest quality and consistency, ensuring uniform performance so that you can be confident with your results which are as accurate as can be.

Quantitative weight has a full flow rate. There are many options for the fast flow filter paper, medium flow filter paper, and slow flow filter paper.
