KIMAX funnel constructed with heavy uniform walls and molded rims and fire polished stems to give a long service life. The 58-degree funnel angle is a Kimble exclusive, formed to an exact angle for rapid filtration. It is more effective than 60 degree angle funnels 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 B requirements.
