Beschrijving
Receiving flask according to Schlenk, cylindrical, 50 ml with NS 14/23 joint is specialised laboratory glassware for inert-atmosphere and vacuum applications. This cylindrical round-bottom vessel incorporates a lateral stopcock with hollow plug and glass handle, allowing controlled isolation and transfer of air- or moisture-sensitive materials. The stopcock bore is 2,5 mm; the side connection uses an NS 14,5 joint fitted with an 8 mm olive for secure tubing attachment. Overall dimensions of 145 × 32 mm keep the flask compact for small-scale Schlenk-line work, distillations and preparative synthesis. Offered as a single piece from manufacturer Witeg, it is well suited to collecting condensates and reaction products under reduced pressure or inert gas. The cylindrical body and round bottom support even heating and efficient stirring when used with standard laboratory heating and stirring equipment. Typical applications include organic synthesis, organometallic chemistry and any workflow that requires reliable exclusion of oxygen and moisture while remaining fully compatible with common ground-joint assemblies.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

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