Product Description
Charging a flask with powder can take a long time when air has to escape through the same opening. This funnel adds a hose connection so vacuum can be applied, drawing solids into the vessel and cutting filling time roughly in half.
This listing is for Kimble catalog number 629700-0018: Jointed Addition Funnel, 24/40. The funnel is made from 33 expansion low-extractable borosilicate glass that meets USP Type I and ASTM E438 Type I, Class A. It has a 24/40 standard taper inner joint, a 60 degree side angle for good powder flow, and a hose connection for 1/4 inch ID tubing. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
