Beschreibung
Receiving flask Schlenk 25 ml NS 14/23 is a round Schlenk-style collection flask engineered for small-scale vacuum and inert-gas operations. The principal neck carries a standard ground joint NS 14/23, complemented by a side stopcock NS 14,5 that enables precise control of atmosphere or vacuum. The stopcock is equipped with a 2,5 mm bore, an 8 mm olive angled at 45°, a hollow plug and a glass handle for reliable handling. Made from borosilicate glass 3.3, the vessel delivers the chemical inertness and thermal stability expected in contemporary organic synthesis. Its nominal volume of 25 ml and net weight of 0,05 kg make it well suited for preparative distillations, solvent recovery and temporary storage of air-sensitive intermediates. This Schlenk receiving flask from manufacturer Witeg fits seamlessly into standard ground-joint apparatus and Schlenk lines. The round body geometry promotes efficient condensate collection while the side arm maintains a gas-tight connection. Supplied as one piece, it serves laboratories that require compact, high-quality glassware within the categories of round-bottom flasks, ground-joint flasks, distillation flasks and receiving flasks.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask Schlenk 25 ml ST 14/23 lat.
What is this article?
Collecting flask Schlenk 25 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.
