Description
Separating funnel 500 ml is a conical laboratory funnel manufactured from borosilicate glass 3.3 according to DIN ISO 4800 and provided with blue graduation. It features a stopcock with NS PTFE plug, stopcock joint NS 18,8 and bore 4,0 mm, plus a PE stopper NS 29/32. The nominal volume of 0,5 l and clear blue scale markings support volume estimation during liquid-liquid extractions, phase separations and solvent washing in organic and analytical laboratories. Conical form promotes efficient drainage and easy visualisation of interfaces between immiscible layers. The PTFE plug ensures controlled, chemically resistant shut-off for accurate release of the lower phase. Offered as one piece from manufacturer Marienfeld, this graduated funnel is well suited to preparative workflows, sample clean-up and teaching laboratories that require both separation capability and approximate volume indication. Construction in borosilicate glass 3.3 meets the material requirements of the referenced DIN ISO standard for everyday laboratory service.

Questions about Separatory funnels 500 ml,
What is this article?
Separatory funnels 500 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.
