Description
Receiving flask according to Schlenk, cylindrical, 100 ml with NS 14/23 joint is laboratory glassware intended for vacuum and inert-gas techniques. The cylindrical round-bottom design includes a side stopcock with hollow plug and glass handle, enabling precise isolation and transfer of sensitive liquids or condensates. Stopcock bore diameter is 2,5 mm, and the lateral arm carries an NS 14,5 joint with an 8 mm olive for tubing connection. Measuring 165 × 40 mm overall, the flask offers a practical intermediate volume for Schlenk-line distillations, solvent collection and air-sensitive preparative work. Supplied as one piece from manufacturer Witeg, it integrates readily into standard ground-joint apparatus. The round bottom and cylindrical body promote uniform heating and effective mixing when used with conventional laboratory heaters and stirrers. Suitable for organic synthesis, organometallic chemistry and any procedure that demands reliable exclusion of moisture and oxygen while maintaining compatibility with common NS joints and vacuum manifolds.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask cylindrical 100 ml ST 14
What is this article?
Collecting flask cylindrical 100 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 Labware.
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.
