ECO Funnel® is a safety funnel that features a long tube to prevent evaporation, a short airlock tube, and a gasket to help keep fumes safely contained. The larger 8" ECO Funnel includes an additional safety feature to prevent over-filling that the 4" version does not have; the secondary air-lock tube creates a small air gap in your waste container, which causes fluid to back up temporarily into the funnel when the container is full. After the screw cap adapter is loosened, the remaining fluid will safely flow into the container and not spill. Protect your lungs, prevent lab fires, and keep chemicals out of the water supply!

The ECO Funnel is the ultimate lab safety product for collection of hazardous liquid waste. Its unique, patented design performs two functions, acting as both a sealed waste container and also as a solvent funnel. The 8" ECO Funnel® is made of HDPE and has a 2 Liter fluid capacity. This solvent waste funnel with lid is designed with a custom screw cap which secures it to a specified waste container. It also features a gasket inside the lid. A removable filter is also built into the interior to reduce the loss of stir bars or other large particles in the waste liquid. The ECO Funnel is a pass-through system, meaning chemicals are not sitting in the funnel for any length of time, so it's HDPE construction is compatible with most solvents including those that need to be stored in glass.

ECO Funnel FAQ

Does the ECO Funnel® comply with regulations for emissions from open waste containers?
Yes. The primary function of the ECO Funnel is to reduce the emission of volatile solvents to near zero, while providing a convenient way to handle temporary waste in the lab.

Are there any chemicals that should be avoided when using the ECO Funnel®?
Yes, you should avoid strong acids, bases and oxidizers that can jeopardize HDPE.

Can the ECO Funnel® be kept on the waste bottle 24 hrs a day?
We recommend that the ECO Funnel be removed from a waste container when not in use, just like any other funnel. They are for the collection of temporary waste only. Waste should be frequently transferred to a more permanent waste container for optimum safety.

Segregate your waste streams with color-coded ECO Funnels. Every organization has its own color-coding rules and systems in place, but proper segregation of hazardous waste is required for all laboratories. One popular way to color-code chemicals is described to the right. You can use our four lid colors to keep certain waste streams separate. Common chemical waste disposal rules to follow:

  • Segregate acids from bases
  • Segregate oxidizers from organic solvents
  • Segregate flammable liquids from acids, bases, oxidizers
  • Segregate corrosives acids from flammables, bases, oxidizers
  • Segregate corrosive bases from oxidizers and acids
  • Segregate water-reactive from aqueous solutions and oxidizers
Common Color
Coding Systems
  Red = flammables
  Blue = toxic (chloroform, cyanide, heavy metals) or corrosive and/or aqueous
  Yellow = reactive
  Green - General low hazard chemicals or oxidizing agents
