Description
Schlenk receiving flask 50 ml NS 14/23 with straight angle valve stopcock is a round laboratory flask for collecting distillates and handling materials under vacuum or inert atmosphere. It carries a standard ground joint NS 14/23 and is equipped with a straight angle valve stopcock of the Economy type fitted with a PTFE spindle. The stopcock bore is 3 mm and the lateral olive measures 8 mm, enabling reliable tubing connections to vacuum lines or inert-gas supplies. Manufactured from borosilicate glass 3.3, the flask combines chemical resistance with thermal stability suitable for everyday laboratory use. Supplied as a single piece with a net weight of 0,046 kg, this receiving flask from manufacturer Witeg belongs to the range of ground-joint and distillation glassware used in preparative work. The round-bottom geometry supports even heating and efficient collection of fractions or reaction products. With its 50 ml capacity it is practical for small-scale organic and inorganic synthesis, fraction collection and classic Schlenk techniques that require isolation from air or moisture. Typical applications include round-bottom flask duties, ground-joint assemblies, distillation setups and dedicated receiving positions on laboratory benches.

Questions about Ballon collecteur Schlenk 50 ml ST 14/23 droit
What is this article?
Ballon collecteur Schlenk 50 ml ST 14/23 droit is the article on this page. Luminix Health distributes Witeg 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.
