CP Lab Safety ECO Funnel®, 8 inch

ECO Funnel® is the original screw-on safety funnel with a lid for laboratory waste disposal. Each model fits a specific container. This 8" ECO Funnel is designed to fit heavy-duty plastic bottles with a 38-430 closure or a glass jug with a GL38 or 38-439 closure. (Please note: when using on glass, gently secure the funnel without over-tightening to avoid damage to the blue screw cap.) Designed by CP Lab Safety, ECO Funnels feature specialized tubes, a latching lid, and gaskets to keep waste fumes contained. A removable large particle filter catches stir bars or other items. A long tube extends into the waste container to minimize chemical evaporation. A secondary air-lock tube is an additional safety feature in the 8" models that protects against over-filling; it creates a small air gap inside your waste container, causing fluid to back up temporarily into the funnel when the it's nearly full. After the screw cap adapter is loosened, the remaining fluid will safely flow into the container and not spill. The smaller tube also acts as an anti-burp mechanism, allowing for the smooth addition of solvent.
