Description
Filter funnel, porosity 4, DURAN® is a laboratory glass funnel designed for filtration of moderate sample volumes. It provides a capacity of 25 ml, an overall diameter of 55 mm and a height of 100 mm, giving a practical working size for routine nutsche-style and Büchner-related filtration. Porosity grade 4 suits finer filtration tasks in chemical and analytical laboratories. Manufactured from DURAN® glass, the funnel is supplied as 1 pc and weighs 0,026 kg. This filter funnel from manufacturer Lenz integrates with filter crucibles, suction bottles and related laboratory glassware used for solids isolation and sample clean-up. The defined overall diameter and height support stable placement and clear observation during filtration. It is appropriate for preparative work, teaching laboratories and quality-control procedures that require a fritted funnel with porosity 4. Compact yet larger than micro formats, the 25 ml volume balances sample capacity with manageable glassware dimensions for everyday bench use. The single-piece supply format simplifies ordering for laboratories that maintain stocks of porosity-graded filter funnels for repeated analytical and preparative filtration steps.
This article is part of Büchner & filter funnels, in Funnels.

What is this article?
Filter funnel, porosity 4, DURAN®, vol. 25 ml, overall-Ø 55 mm, H 100 mm is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Büchner & filter funnels, inside Funnels, in Labware.
A Büchner funnel is a perforated porcelain or plastic plate used with a rubber cone and vacuum to pull liquid through a filter paper. A filter funnel is the glass cone that holds a folded paper under gravity. The plate diameter decides the paper size.
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.
