Kimble 28900 KIMAX Long Stem Filling Funnels with 58° Angle and 150mm Long Stem are constructed with heavy uniform walls and strong, molded rims. Fire polished stems give a long service life. Funnels have a high resistance to chemical attack and mechanical and thermal shock. The 58° funnel angle is a Kimble exclusive, formed to an exact angle for rapid filtration. 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. The exclusive KIMAX 58...Catalog No.: F4430-3 | F4430-4 | F4430-5 | F4430-7
