Description
Separating funnel 500 ml Squibb type is a graduated laboratory glassware item designed for efficient liquid-liquid extractions and phase separations. Constructed from borosilicate glass 3.3, it offers a nominal volume of 0,5 l and incorporates a PTFE key stopcock of NS 14,5/4 mm bore for chemical inertness and precise flow regulation. The unit is supplied with a PE stopper matching the NS 29/32 ground joint, providing a secure closure during mixing and equilibration. This Squibb-pattern funnel from manufacturer Rettberg features clear graduations that enable reliable volume assessment in extraction, washing and partitioning operations. Its durable glass body resists the thermal and chemical stresses common in organic synthesis, analytical work-up and quality-control environments. With a net weight of 0,306 kg the funnel remains practical for everyday bench use while preserving the mechanical integrity of borosilicate 3.3. Compatible with both aqueous and organic media, it supports reproducible phase separation across research, industrial and teaching laboratories.

Questions about Separatory funnel, 500 ml, Squibb, grad., PTFE plug size 14,5/4 mm,
What is this article?
Separatory funnel, 500 ml, Squibb, grad., PTFE plug size 14,5/4 mm, is the article on this page. Luminix Health distributes Rettberg 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.
