Description
Separating funnel, 100 ml, pear-shaped (BF), graduated, with PTFE key NS 12,5/2,5 mm provides a practical mid-size vessel for liquid-liquid extractions and phase separations in the laboratory. Fabricated from borosilicate glass 3.3 to ISO 4800, the funnel carries clear graduation marks that support precise volume assessment. A chemically inert PTFE stopcock key with 12,5/2,5 mm bore delivers reliable flow regulation, while the NS 19/26 ground joint is closed by a PE stopper. With a nominal volume of 0,1 l and a net weight of 0,124 kg, this 100 ml model balances capacity and handling convenience. The pear-shaped body encourages clean layer separation, and the borosilicate construction offers the thermal and chemical resistance expected in everyday organic synthesis, analytical sample preparation and teaching applications. Available as a single piece from manufacturer Rettberg, the funnel is ready for immediate use with aqueous or organic media and is easy to clean after each separation run.

Questions about Separatory funnel, 100 ml, conical, grad., PTFE plug size 12,5/2,5 mm,
What is this article?
Separatory funnel, 100 ml, conical, grad., PTFE plug size 12,5/2,5 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
