Receiving flask according to Schlenk 100 ml cylindrical NS 29/32 is a specialised laboratory glass vessel for collecting distillates under vacuum or inert atmosphere. The cylindrical body with round bottom carries a ground joint sleeve NS 29/32 for direct connection to standard Schlenk and distillation apparatus. A lateral stopcock fitted with hollow plug, glass handle and 2,5 mm bore permits controlled isolation or transfer of contents, while the side arm provides an NS 14,5 joint completed by an 8 mm olive for tubing. Overall dimensions are 160 × 40 mm. Supplied as a single piece with nominal volume 0,1 l and net weight 0,131 kg, the flask integrates readily into existing ground-joint systems. This design from manufacturer Witeg supports reliable performance in organic synthesis, solvent removal and air-sensitive reagent handling. The robust construction ensures secure assembly within distillation trains and Schlenk lines commonly used in research and preparative laboratories, offering precise volume control and compatibility with standard laboratory tubing and joints.
This article belongs on Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask cylindrical 100 ml ST14
What is this article?
Collecting flask cylindrical 100 ml ST14 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.
