Description
Bunsen funnel 70 mm Ø is a laboratory glass funnel made from borosilicate glass 3.3 in accordance with DIN 12 446. It features smooth surfaces and an approximately 150 mm long stem that supports controlled liquid transfer and gravity filtration in analytical and preparative workflows. The 70 mm rim diameter provides a practical opening for pouring samples, solvents and reagents into receiving vessels or filter assemblies while the elongated stem directs flow accurately. Produced by manufacturer Marienfeld, the funnel combines the chemical resistance and thermal stability typical of borosilicate glass 3.3 with consistent geometry for everyday laboratory use. Supplied in packs of 10 pieces, these funnels are suited to research, teaching and quality-control environments. Smooth internal and external surfaces help minimise residue retention and simplify cleaning between runs. The design is appropriate for routine decanting, filtration and general liquid handling of aqueous media and many organic solvents. Robust construction ensures dimensional reliability under normal laboratory conditions, making the Bunsen funnel a dependable component of standard glassware sets for reproducible sample preparation.
