Temporarily contain waste on the benchtop or under the lab hood using Thermo Scientific™ Nalgene™ Safety Waste Funnel Systems. Funnels feature the Easy Snap Safety Latch to minimize spillage if accidentally tipped over and a larger diameter funnel for easy pouring. The vent system helps reduce fumes and splashing while the removable neck screen traps large particles, like stir bars. Designed for solvent, chemical and biological waste, it is recommended for use with Nalgene containers.
