Description
Filter funnel of borosilicate glass 3.3 with 75 ml capacity, model 11 D and porosity 4, is designed for vacuum-assisted filtration in laboratory solid-liquid separations. This glass nutsche features a fritted disc of porosity grade 4, appropriate for finer particle retention and more demanding filtration tasks involving smaller precipitates. Made from robust Boro 3.3, it combines chemical durability with thermal resistance suitable for everyday analytical and preparative workflows. The 75 ml volume is convenient for small-scale sample work, residue collection and controlled filtrate recovery under vacuum. Supplied as one piece, the funnel integrates with conventional laboratory vacuum filtration assemblies. From manufacturer Brand, the model 11 D configuration delivers reproducible performance through the sintered glass plate while the transparent body permits continuous visual checks during operation. It serves research, teaching and industrial quality-control laboratories that need a compact, chemically resistant glass filter funnel with porosity 4 characteristics.
