Eco Funnels are made of HDPE.

Funnels feature an easy to use lid. A gasket and positive latch close the lid and maintain an airtight seal. A filter is also built into the interior to reduce the loss of magnetic stir bars and other items when emptying the contents of a vessel into the funnel. The funnel is equipped with an 11" stem to reduce chemical evaporation of hazardous solvents in the lab.
