The funnel includes an easy-to-click safety latch to minimize accidental spills and a larger diameter funnel for easier filling. The ventilation system helps reduce smoke and splash, and the removable neck screen captures large particles such as stirrers. Designed for solvents, chemicals and biochemical waste, recommended for use with Nalgene containers.
