Stainless Steel Tri-Clamp Hopper

Works great for loading my Bio reactor. Narrow enough to not hit my overhead mixer. The Down side is the price,but it was the only tri clamp funnel on the market that would work in my situation. It was worth the money for my bio reactor to be able to load biomass while running the stir bar with solvent loaded. It was a must have in my situation and worth the cost to solve loading the reactor with such a compact 1 1/2" port. The funnel is totally secure to the reactor and you can load easily because it is secured via tri clamp 🗜️ makes it easier to tamp down the biomass through the 1 1/2" opening without it flopping around like a plastic funnel... Works perfectly!!! Would definitely buy again for tight situations on a reactor lid.. Cleantech LLC
