Description
Separating funnel 1000 ml is a conical laboratory funnel manufactured from borosilicate glass 3.3 in accordance with DIN ISO 4800. With a nominal volume of 1 l, it is designed for reliable liquid–liquid extractions and phase separations in analytical and preparative chemistry. The stopcock features an NS PTFE plug with a 4,0 mm bore and an NS 18,8 ground joint, ensuring smooth, chemically resistant operation and a secure seal. Blue graduation markings support convenient volume reading during work-up procedures. A poly stopper NS 29/32 completes the closure system for the upper neck. Supplied as a single unit from manufacturer Marienfeld, this separating funnel combines mechanical strength, thermal resistance and chemical durability typical of borosilicate glass 3.3. It is well suited for routine solvent extractions, washing steps and sample preparation in research, quality-control and teaching laboratories where clear phase boundaries and controlled drainage are required.

Questions about Separatory funnels 1'000 ml,
What is this article?
Separatory funnels 1'000 ml, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Ampoules à décanter, inside Entonnoirs, in Matériel de laboratoire.
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.
