Product Description
Crowded multi-neck flasks leave little room for a full round funnel next to a condenser or stirrer. These addition funnels have a flattened side that sits closer to neighboring glassware, so you can charge powders through a 24/40 joint without removing other accessories.
This listing is for Kimble catalog number 629200-0018: Jointed Addition Funnel, 75 mm Top OD. The funnels are made from 33 expansion low-extractable borosilicate glass that meets USP Type I and ASTM E438 Type I, Class A. The flat side is 25 mm from the center of the 24/40 inner joint, letting the funnel clear adjacent necks. Top diameters of 75 mm and 100 mm are offered. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
