Beschreibung
Schlenk receiving flask 50 ml with NS 14/23 joint is a round laboratory vessel intended for collecting distillates and handling air-sensitive compounds under inert atmosphere. It combines a standard ground joint NS 14/23 with a lateral stopcock NS 14,5 that has a 2,5 mm bore and an 8 mm olive angled at 45°, allowing secure tubing connections for vacuum or inert gas. A hollow plug and glass handle complete the stopcock assembly for smooth manual control. Produced from borosilicate glass 3.3 by manufacturer Witeg, the flask delivers the chemical durability and thermal shock resistance expected in demanding laboratory environments. The 50 ml nominal capacity and compact 0,056 kg net weight make it practical for small-scale organic synthesis, Schlenk-line techniques and preparative distillation work. Its round-bottom geometry supports uniform heating and efficient stirring when paired with suitable heating equipment. Ideal for research laboratories performing air-free manipulations, this receiving flask integrates readily into existing ground-joint glassware systems used for distillation and reaction work-up.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask Schlenk 50 ml ST 14/23 lat.
What is this article?
Collecting flask Schlenk 50 ml ST 14/23 lat. is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Laborbedarf.
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.
