Description
Funnel 40 mm Ø is a laboratory funnel made from borosilicate glass 3.3 in accordance with DIN 12 445. It offers smooth surfaces, a 60° angle and a short stem that is obliquely ground, where the stem length approximates the diameter. These design elements support reliable filtration and liquid transfer in analytical chemistry and general laboratory workflows. The funnel is packed in units of 10 pieces and comes from manufacturer Marienfeld. Borosilicate glass 3.3 provides strong resistance to chemicals and thermal stress, making the product suitable for everyday use with aqueous solutions, organic solvents and mild reagents. Laboratories employ such funnels for gravity filtration with filter paper, decanting and transferring liquids between vessels. The 40 mm rim diameter fits common small-scale setups while the short stem reduces dead volume and improves handling in fume hoods or on benches. Consistent geometry according to the DIN standard ensures interchangeability and predictable performance across multiple units in a pack.
This article is part of Funnels (plastic, glass & steel), in Funnels.

Questions about Funnels 40 mm Ø,
What is this article?
Funnels 40 mm Ø, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Entonnoirs (plastique, verre & acier), inside Entonnoirs, in Matériel de laboratoire.
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.
