KIMBLE® KIMAX® Borosilicate Glass 6" Long Stem Funnels, 65mm, 58° angle, case/48

The exclusive KIMBLE® 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.

• 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
