The exclusive KIMAX® 58° funnel promotes faster, more effective filtering because the cone is suspended by its uppermost edge

·         A piece of filter paper, when folded to form the filtering cone, makes 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

·         Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements
