Description
Separating funnel 2000 ml is a conical laboratory vessel manufactured from borosilicate glass 3.3 in accordance with DIN ISO 4800. It features a stopcock with NS PTFE plug, blue graduation for clear volume reading, a poly stopper NS 29/32 and a stopcock joint NS 18,8 with 4,0 mm bore. The 2 l nominal volume supports efficient liquid-liquid extractions, phase separations and solvent partitioning in analytical and preparative chemistry. Robust borosilicate construction provides excellent chemical resistance and thermal stability for routine and demanding workflows. Supplied as a single piece from manufacturer Marienfeld, this funnel integrates smoothly into standard laboratory glassware sets. The conical geometry promotes clean phase boundaries and complete drainage, while the PTFE plug ensures reliable, grease-free sealing. Ideal for organic synthesis, environmental analysis and quality-control laboratories requiring precise, reproducible separations.

Questions about Separating funnel 2000 ml, conical, borosilicate glass 3.3
What is this article?
Separating funnel 2000 ml, conical, borosilicate glass 3.3 is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Separating funnels, inside Funnels, in Labware.
A separating funnel lets two immiscible liquids settle into layers and then runs off the lower one through a stopcock. The shape, Squibb or pear, changes how sharp the interface is as the last millilitres leave. The stopper and the stopcock are both needed.
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.
