Description
DURAN® dropping funnel blank, cylindrical with stopper seat for ISO 4800, is a raw glass body with a nominal volume of 100 ml designed for further processing into finished laboratory dropping funnels. Made from borosilicate glass 3.3, the blank features a cylindrical form with stopper seat and is prepared for the attachment of matching standard ground joints according to DIN ISO 4800. Dropping funnels are used for the metered addition of liquids to reaction mixtures in chemical synthesis and laboratory work. Once finished, the cylindrical geometry supports controlled dosing and phase-related operations. This unfinished glass article from manufacturer Duran/DWK Life Sciences is supplied as a Rohkörper for professional further processing, allowing glass workshops to complete ISO-compliant dropping funnels. End applications after conversion include dosed liquid feed and phase separation setups. The blank provides the chemical and thermal durability expected of DURAN® borosilicate glass 3.3 and serves as a consistent starting component for laboratory glassware fabrication. Net weight is 0,08 kg per piece; the product is offered in packs of 10 pc(s) for efficient workshop use.
This article is part of Dropping funnels, in Funnels.

Questions about DURAN® Blank for dropping funnel, cylindrical, with stopper bed for ISO 4800
What is this article?
DURAN® Blank for dropping funnel, cylindrical, with stopper bed for ISO 4800 is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Dropping funnels, inside Funnels, in Labware.
A dropping funnel adds a liquid slowly into a closed reaction through a stopcock and usually a ground joint. A pressure-equalising arm keeps the funnel from air-locking. The joint size and the volume are the specification.
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.
