Shop labware funnels designed specifically for funnel chemistry applications. Easily transfer solvents from a wide-mouthed vessel into one with a narrow mouth, like a crucible, graduated cylinder, test tube, beaker, or flask. Our selection includes separatory (Squibb), Buchner, powder, glass, and plastic styles. Available in long stem and short stem designs.
Separatory (Squibb): Available for inorganic and organic chemistry processes. This separating funnel allows you to separate two immiscible liquids of different densities, where the heaver liquid settles at the bottom to easily draw off. Also, use to add a reagent in distillation or a reaction process. A PTFE stopcock is included.
Buchner: Filtration made easy! This special two-piece wide mouth filter funnel is for filtering mixtures through filter paper into a filtering flask. Available in porcelain and polypropylene.
Powder: These short stem funnels are best for transferring powdered reagents. The unique feature is its parallel stem that minimizes the bridging of powder. They are steam autoclavable.
Glass & plastic: Get a glass funnel when you need it to withstand transferring caustic chemicals to bottles. Get a plastic funnel when you need something that won't break when dropped, as young scientists are prone to do.
Our laboratory funnels range in size from 65 mm in diameter to 120 mm in diameter with various stem lengths. They're made of borosilicate glass, porcelain, or plastic. Also shop filter paper and other lab equipment. Check out Home Science Tools' new products and best sellers!
