These funnels have a beaded edge for strength. They are fabricated from blanks formed to a 60° angle which permits accurate fitting of the filter paper thus reducing filtering time. The stems are made of heavy wall tubing approximately 150mm (6") long.

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.
