Description
Funnel with long stem in borosilicate glass 3.3 is a laboratory funnel intended for liquid transfer, gravity filtration and general preparative work at the bench. With an approximate diameter of 8 cm and a long stem, it seats securely in flasks, bottles and filter assemblies while directing flow into the receiving vessel. The Boro 3.3 glass construction matches common laboratory glassware requirements for chemical and thermal durability during routine handling of aqueous media and many laboratory solvents. Offered as a pack of 10 pieces (Hecht), the funnel supports multi-station setups in research, teaching and quality-control environments where several filtrations or transfers run in parallel. The larger approx. 8 cm diameter relative to smaller long-stem funnels provides a wider working surface for filter papers and faster pouring of larger volumes. Classified under laboratory materials, this item is a standard glassware component for sample preparation, solvent addition and filtration workflows. All stated attributes—long stem, Boro 3.3 material and approximate 8 cm diameter—reflect the manufacturer description without added purity, sterility or performance claims.
This article is part of Funnels (plastic, glass & steel), in Funnels.

What is this article?
Funnels, plain, long stem, DIN ISO 4798, Boro 3.3, bowl angle of 60°, Diameter: is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Funnels (plastic, glass & steel), inside Funnels, in Labware.
This is the ordinary funnel, in plastic, glass or steel, used to guide a liquid or a powder into a narrower mouth. The cone angle, the stem bore and the material are the choices. It does not, by itself, filter.
A funnel guides a liquid or a powder into a narrower mouth. A filter funnel holds a paper. A Büchner funnel is the flat perforated plate used with vacuum. A separating funnel has a stopcock so two liquid layers can be run off one at a time. A dropping funnel adds a reagent slowly into a reaction. The bore and the stopcock are the parts that matter. This glassware is listed under ISO laboratory glassware.
