This 4" ECO Funnel® system includes a 20 Liter Baritainer®* which has the equivalent chemical resistance of a Fluorinated HDPE Drum, although it is not truly fluorinated (subject to fluorine gas.) The container features a 70mm, 6-TPI buttress closure. Our patented design features a latching lid with gasket to keep fumes contained. A removable large particle filter catches stir bars or other items. A detachable tube extends into the waste container and reduces chemical evaporation. Customize with HPLC

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 4" ECO Funnel® is made of HDPE and has a 450 mL fluid capacity. This solvent waste funnel is designed with a custom screw cap which secures it to a specified waste container. It also features a closed-cell HDPE gasket inside the lid and a sturdy positive latch which ensures the lid remains securely closed. 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 its HDPE construction is compatible with most solvents including those that need to be stored in glass.

Benefits of Baritainers®

A Baritainer is made of a barrier resin and provides an alternative to fluorination. Each blow-molded container is UN X rated and features a molded-in handle. The combination of HDPE and Quoral® provide and excellent alternative for storing chemicals that usually require glass, metal, or fluorinated HDPE. Baritainers are impact resistant, lightweight, rugged, economical & stackable. Baritainers are effective containers for solvents, esters, ketones and some acids.

Bartainers® are constructed of regular HDPE mixed with a proprietary barrier resin and are a safe substitute for fluorinated containers. Made of 95% HDPE 95% and 5% QUORAL BR50, the Jerry Can style of Bartainer® is roughly 50% lighter than a metal container and will not panel, distort or lose product when sealed. They prevent chemical permeation, weight loss, odor emission and flavor or fragrance loss and are both UN rated and FDA compliant.

In comparison with HDPE, Quoral® is 100x more efficacious with Hydrocarbons (solvents) , provides an excellent aroma barrier, and features 2x to 5x improvement in barrier performance.

QUORAL® (pat. pend.) based Jerricans can be used to safely transport solvent-based products such as household chemicals, industrial chemicals, cleaning solvents, adhesives, wood preservatives, automotive additives, and agricultural chemicals. They may also be used to safely transport foodstuffs such as flavors, edible oils and essential oils.

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.
