Buchner Funnel (All-glass Vacuum Filtration Set) Honeycomb filter

A complete all-glass vacuum filtration system consisting of a honeycomb 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.

KEY COMPONENTS
