DURAN® Analytical Funnel manufactured by DWK Life Science is made from 3.3 expansion borosilicate glass. The internal glass moulding lifts the filter paper away from the funnel walls allowing faster filtration than with a normal funnel. It also can be used to transfer a relatively large amount of solids and powders into a vessel with a small opening.
