ECO Funnels are widely used in laboratories worldwide. The smallest size, our 4 inch ECO Funnel, is available with a variety of custom screw caps that fit most common waste containers. Amber glass solvent bottles can usually accept our basic model # EF-4-38.
Review the chart on this page https://www.calpaclab.com/choosing-the-right-eco-funnel/ if you need assistance. If you cannot find the right funnel for your container, request a quote for a custom screw cap (minimum order required.)
4 inch ECO Funnels are popular because they are several inches shorter than the 8 inch model and thus fit more easily in smaller fume hoods. However, do to their small size, they do not include the overfill protection mechanism that the larger funnel features.
