Filter Funnel, 500 ml, Por. F

Filter funnel 500 ml, porosity F is a laboratory filtration vessel manufactured from borosilicate glass 3.3 and fitted with an integrated VitraPOR® sintered filter plate of 95 mm diameter. The working height above the filter plate measures 100 mm, providing ample space for sample loading and washing steps during vacuum filtration. This Büchner-type filter nutsche from manufacturer ROBU - Stereon is intended for solid-liquid separations in chemical synthesis, analytical sample preparation and routine laboratory workflows. Porosity grade F defines the pore characteristics of the frit, enabling retention of crystalline solids and particulate matter while permitting free passage of filtrate under reduced pressure. The 500 ml nominal capacity suits medium-scale batches commonly processed in research and quality-control environments. Chemical resistance of the borosilicate construction supports use with a wide spectrum of aqueous and organic media. The robust one-piece design with permanently fused filter disc eliminates the need for loose filter papers in many applications and ensures consistent performance over repeated cycles. The funnel is readily combined with standard filter flasks and vacuum adapters to form complete filtration assemblies.
