Description
Slotted sieve filter (Büchner funnel) DURAN® is a laboratory glassware funnel designed for vacuum-assisted filtration with filter media of 90 mm diameter and a working capacity of 500 ml. The slotted sieve plate supports filter papers or glass fibre filters during solid–liquid separations under reduced pressure, a standard technique in analytical and preparative chemistry. Manufactured from DURAN® borosilicate glass by DWK Life Sciences, the funnel integrates into typical Büchner setups used with vacuum flasks and pumps. It suits routine filtration of precipitates, suspensions and process samples where a defined filter diameter and moderate volume are required. The unit is supplied as a single piece with a net weight of 0,500 kg, making it practical for benchtop use in teaching, quality-control and research laboratories. Categories of use include vacuum technology and filtration workflows that rely on glass fibre or paper filters. Clear dimensional matching of the 90 mm filter seat helps ensure even support of the filter disc and reproducible cake formation during suction filtration.
This article belongs on Büchner & filter funnels, in Funnels.

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.
