Description
The 1000 ml conical graduated separating funnel is a precision borosilicate glass vessel for liquid-liquid extractions and phase separations in the laboratory. Clear graduations support accurate volume reading while the conical body promotes clean interface formation between immiscible solvents. It is fitted with an NS-PTFE stopcock plug that has a 6,3 mm bore for controlled draining and an NS-PE stopper on the NS 29/32 joint for secure closure. Supplied as a pack of 2 pieces with a net weight of 0,291 kg, the funnel offers chemical resistance and mechanical durability for routine analytical and preparative work. This laboratory glassware from manufacturer Witeg is well suited to extraction protocols, solvent partitioning and teaching applications that demand reliable sealing and easy cleaning. The standardised ground joints ensure compatibility with common laboratory stoppers and adapters, allowing straightforward integration into existing glassware sets.

Questions about Separatory funnel 1000 ml con. ST-PTFE graduated
What is this article?
Separatory funnel 1000 ml con. ST-PTFE graduated is the article on this page. Luminix Health distributes Witeg 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.
