KIMAX® funnel constructed with heavy uniform walls and strong, molded rims and fire-polished stems to provide 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

·         Designed from ASTM Specification E1095, Type I, Class B requirements

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