Description
Separating funnel, 2000 ml, pear-shaped (BF) and graduated, is designed for larger-scale liquid–liquid extractions and phase separations. Constructed from borosilicate glass 3.3, it features a solid glass key stopcock of NS 18,8/6 mm bore and a PE stopper with NS 29/32 joint. The funnel meets ISO 4800 requirements and is graduated to allow convenient volume monitoring throughout the separation process. With a nominal volume of 2 l and a net weight of 0,820 kg, the pear-shaped body accommodates substantial sample volumes while still permitting clean layer division. Available as a single unit from manufacturer Rettberg, it combines the chemical resistance and thermal stability of borosilicate glass 3.3 with a durable stopcock suitable for frequent laboratory use. Ideal for preparative chemistry, process development and quality-control applications that demand reliable phase separation, controlled outflow and compatibility with standard jointed glassware. Graduation marks and robust joints facilitate precise work-up and straightforward integration into existing extraction setups.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Separatory funnel, 2000 ml, conical, grad., glass plug size 18,8/6 mm,
What is this article?
Separatory funnel, 2000 ml, conical, grad., glass plug size 18,8/6 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
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.
