Beschrijving
Receiving flask according to Schlenk 50 ml cylindrical NS 14/23 is a specialised laboratory glass vessel for distillation and inert-atmosphere work. The cylindrical body with round bottom carries a ground joint sleeve NS 14/23 for secure connection to standard Schlenk lines and distillation assemblies. A lateral stopcock with hollow plug, glass handle and 2,5 mm bore, completed by an NS 14,5 connection and 8 mm olive, enables controlled vacuum or gas handling during collection of distillates. Overall dimensions are 145 × 32 mm; nominal volume is 0,05 l and net weight 0,094 kg. This single-piece flask from manufacturer Witeg is intended for receiving fractions under reduced pressure or inert gas in synthetic organic chemistry, vacuum distillation and teaching laboratories. The Schlenk-type layout supports air-sensitive techniques while remaining compatible with common ground-joint glassware. Compact cylindrical geometry aids placement on stands and within fume hoods, making the item a practical component of distillation and Schlenk-line setups.
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.
