Description
Nalgene™ separatory funnel, polypropylene, Teflon™ TFE stopcock and plug is a chemically inert laboratory vessel for liquid-liquid extractions and phase separations. With a nominal volume of 0,125 l (125 mL), the translucent polypropylene body allows clear observation of phase boundaries while remaining fully autoclavable for repeated sterilisation cycles. The funnel is fitted with a Teflon™ TFE stopcock and matching plug together with a polypropylene screw closure, delivering reliable sealing and smooth flow control during draining. These Nalgene™ separatory funnels and closures from manufacturer Thermo Scientific are designed for chemical resistance across a wide range of solvents and reagents commonly encountered in organic and analytical chemistry. Supplied as a single unit (pack configuration also referenced as 1 per pack, 6 per case), the funnel has a gross weight of 0,520 kg and is suited to routine extraction work, sample clean-up and teaching laboratories. The combination of lightweight polypropylene construction, inert TFE stopcock components and autoclavability makes the 125 mL size a practical choice for medium-scale separations where glass alternatives are less desirable.

Questions about Nalgene™ Polypropylene Separatory Funnels with Closure
What is this article?
Nalgene™ Polypropylene Separatory Funnels with Closure is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics 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.
