Description
Separating funnel 1000 ml, pear-shaped and ungraduated, with PTFE key NS 18,8/6 mm is intended for liquid–liquid extractions and phase separations in the laboratory. Made from borosilicate glass 3.3, it adopts the pear-shaped form specified by ISO 4800 and is supplied ungraduated for unobstructed viewing of separation layers. The PTFE key featuring an NS 18,8/6 mm bore provides chemical resistance and smooth, controlled outflow, complemented by a PE stopper with NS 29/32 joint that closes the upper opening. Nominal volume is 1 l and net weight is 0,409 kg; the item is packed as a single piece. The NS 29/32 ground joint guarantees interchangeability with common laboratory stoppers. Offered by manufacturer Rettberg, this funnel unites the mechanical and chemical robustness of borosilicate glass 3.3 with the inert characteristics of a PTFE stopcock. Its pear-shaped body assists efficient phase collection and thorough drainage, making it well suited to everyday analytical and preparative separation tasks that demand durable, chemically resistant glassware.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Separatory funnel, 1000 ml, conical, non-grad., PTFE plug size 18,8/6 mm,
What is this article?
Separatory funnel, 1000 ml, conical, non-grad., PTFE 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 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.
