Description
Separating funnel, 2000 ml, pear-shaped and ungraduated, offers generous capacity for larger-scale liquid-liquid extractions and phase separations in the laboratory. Fabricated from borosilicate glass 3.3, the unit includes a solid glass key stopcock with NS 18,8/6 mm bore and a polyethylene stopper of NS 29/32. Its pear-shaped (BF) profile encourages sharp phase boundaries and smooth drainage of the lower layer. The funnel conforms to ISO 4800 and is supplied without graduations, making it suitable when volume control is handled by other means. Nominal volume is 2 l and net weight is 0,813 kg; packing unit is one piece. Borosilicate glass 3.3 delivers the chemical resistance and mechanical robustness expected for organic work-up, environmental sample processing and preparative chemistry. From manufacturer Rettberg, the funnel fits conventional ground-joint laboratory assemblies. Secure closure by the PE stopper and precise control via the glass stopcock support confident shaking and settling steps in extraction protocols.

Questions about Separatory funnel, 2000 ml, conical, non-grad., glass plug size 18,8/6 mm,
What is this article?
Separatory funnel, 2000 ml, conical, non-grad., glass plug size 18,8/6 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.
