A complete all-glass vacuum filtration system consisting of a sintered (fritted) glass Büchner funnel integrated with a vacuum filtration flask via a standard ground glass joint.
Unlike porcelain Büchner funnels that require filter paper, this unit features a porous glass disc (G-grade frit) enabling direct filtration without filter paper, ideal for fine precipitates and analytical workflows.
