Description
Funnel with long stem, Boro 3.3, diameter approx. 4 cm is a borosilicate laboratory funnel for everyday pouring, decanting and gravity-filtration tasks. Constructed from Boro 3.3 glass, it provides the thermal shock resistance and chemical robustness typical of standard laboratory glassware used with aqueous media and many routine reagents. The approximate 4 cm diameter offers a slightly larger working opening for small- to medium-volume transfers, while the long stem guides liquid smoothly into narrow-neck flasks, bottles or receivers and helps limit spillage. Packaged as 10 pieces from manufacturer Hecht, the funnel is convenient for multi-user benches, student practicals and quality laboratories that keep several identical funnels on hand. Its straightforward long-stem design pairs readily with filter paper for simple separations and supports clean transfer between vessels without extra adapters. Compact and easy to clean, it integrates well with other borosilicate glass items in general lab material inventories. Choose this funnel when a durable, approximately 4 cm long-stem glass funnel is required for reliable day-to-day liquid handling.
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.
