Powder Funnels
When pouring large particles into reaction vessels, powder funnels allow a clean and quick procedure. Manufactured from clear glass or indestructible plastic, powder funnels have a resistant construction permitting use with various reagents and even chemicals. Powder bridging is minimized by the parallel, short stems. The funnels may have a tapered or angled stem to accommodate neck openings. Featuring ribbing to release air, the disposable or reusable models are offered in various diameter sizes.
