Choosing the Right ECO Funnel
We make an ECO Funnel® for each of the common laboratory waste container, from 4 liter glass solvent bottles to drums to Nalgene® 20 liter plastic carboys. Use the guide below to choose which ECO Funnel will fit your waste container.
This chart shows our most popular models and the containers they fit. However, we have many other options for less common waste containers which can be seen below in the visual charts. Please contact us with questions and customization requests.
