Description
Receiving flask according to Schlenk, cylindrical 100 ml with NS 29/32 ground joint is laboratory glassware designed for collecting distillates and reaction products under inert or vacuum conditions. The vessel combines a round bottom with a cylindrical body and is fitted with a lateral stopcock that includes a hollow plug and glass handle. Stopcock bore is 2,5 mm; the side connection uses an NS 14,5 joint together with an 8 mm olive for tubing. Overall dimensions are 160 x 40 mm. Supplied as a single piece, the flask supports classic Schlenk-line techniques for air- and moisture-sensitive work. Its geometry allows secure isolation of fractions while permitting controlled evacuation or inert-gas exchange. Produced by manufacturer Witeg, the item integrates readily into standard ground-joint distillation and vacuum-transfer assemblies. Suitable for organic synthesis, organometallic chemistry and preparative distillation, this receiving flask provides a practical solution for laboratories that require reliable inert-atmosphere handling of liquids in compact scale.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask cylindrical 100 ml ST 29
What is this article?
Collecting flask cylindrical 100 ml ST 29 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.
