Description
Receiving flask according to Schlenk, cylindrical, 200 ml with NS 14/23 joint is a glass laboratory vessel designed for inert-atmosphere and vacuum operations. Its cylindrical round-bottom form is equipped with a lateral stopcock featuring a hollow plug and glass handle, permitting controlled isolation and transfer of air-sensitive or moisture-sensitive materials. The stopcock bore measures 2,5 mm; the side arm is finished with an NS 14,5 joint and an 8 mm olive for secure hose connection. Overall dimensions of 210 × 40 mm provide ample capacity for medium-scale Schlenk-line distillations, condensate collection and preparative synthesis. Available as a single piece from manufacturer Witeg, the flask fits standard ground-joint assemblies used in organic and organometallic laboratories. The round bottom and cylindrical wall support even heat distribution and efficient stirring with conventional laboratory equipment. Ideal wherever reliable exclusion of oxygen and moisture is required while retaining full compatibility with common NS joints, vacuum manifolds and inert-gas lines.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask cylindrical 200 ml ST 14
What is this article?
Collecting flask cylindrical 200 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.
