Kimax 28950-25 Glass Funnel, with Short Stem, 25mm ID (Case of 24)

Kimax Short stem funnel is constructed with heavy uniform walls, strong molded rims and fire polished stems to give a long service life. The 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° funnel promotes faster, more effective filtering because the cone is suspended by its uppermost edge, leaving most of the conical area for filtration. Designed from ASTM Specification E1095, Type 1, Class A requirements. Approx. Internal Diameter at Top: 25mm. Fits Paper with Diameter: 42.5mm. Cone Volume: 3mL. Length of Stem: 40mm. Approx. Outer Diameter of Stem: 6mm. Kimble #: 28950-25.
