Funnel, Buchner Polypropylene 70mm Inside Diameter.

GSC International BFP70 Buchner Funnel Polypropylene 70mm Inside Diameter. The polypropylene Buchner funnels are two-piece, lightweight, and easy-to-clean. The top portion snaps into the bottom forming a vacuum tight seal. The funnel has an opening with an inside diameter of 70mm. And they are fully autoclavable. Vacuum Filtration:Primarily used for vacuum-assisted filtration, allowing students and lab technicians to quickly and efficiently separate solids from liquids by applying a vacuum source beneath the funnel. Durable and Chemical-Resistant for Teaching Labs:The polypropylene construction makes it lightweight, shatter-resistant, and resistant to a wide range of chemicals, which is especially useful in busy teaching labs where durability is important. Demonstrations of Filtration Principles:Ideal for classroom demonstrations to show basic scientific principles such as gravity filtration versus vacuum filtration, phase separation, and material recovery processes. Great for demonstr
