Powder funnel is constructed with heavy uniform walls, molded rims and fire-polished stems to give a long service life.

·         Funnels have a high resistance to chemical attack and mechanical and thermal shock

·         A piece of filter paper, when folded to form the filtering cone, forms a precise 60° angle. If the funnel is also 60°, as are the vast majority, then the only effective filtering area is down near the tip

·       Powder funnel promotes faster, more effective filtering because the cone is suspended by its uppermost edge, leaving most of the conical area for filtration
