Filtering Manifold for Determining the Fibrous Composition of Feeds

Abstract

Analysis of the fibrous composition of feeds by the Goering and Van Soest procedure requires that samples be filtered in the presence of mineral acids and organic solvents. In this process, it is desirable to use a manifold that not only is resistant to these reagents, but also is inexpensive and easy to construct. The new design fits Gooch crucibles tightly and eliminates vacuum leaks and the associated foaming that hampers filtration of difficult samples.
