VWR Buchner Filter Funnel 350 ml Medium Porosity Fritted Disk

Description

The VWR 89000-448 Buchner Filter Funnel is a 350 mL capacity laboratory funnel made from borosilicate glass. This type of glass is chosen for its excellent chemical resistance, thermal durability, and ability to withstand the vacuum conditions typically used with a Buchner funnel. A defining characteristic of this specific funnel is its medium porosity fritted disk. A fritted disk, or sintered glass filter, is a porous glass disc permanently fused into the funnel, eliminating the need for separate filter paper.
