Beschreibung
Schlenk receiving flask 100 ml NS 14/23 with straight angle valve stopcock is a round laboratory flask intended for distillate collection and work under reduced pressure or inert gas. The vessel features a standard ground joint NS 14/23 together with a straight angle valve stopcock of the Economy series that incorporates a PTFE spindle. Stopcock bore diameter is 3 mm and the side olive is 8 mm, providing secure attachment points for vacuum or gas tubing. Made from borosilicate glass 3.3, the flask offers the chemical durability and thermal-shock resistance expected in routine laboratory operations. Delivered as one piece with a net weight of 0,078 kg, this receiving flask from manufacturer Witeg forms part of the ground-joint and distillation glassware family used in preparative chemistry. Its round bottom promotes uniform temperature distribution during heating or cooling steps. The 100 ml working volume suits medium-scale synthetic procedures, fraction collection and Schlenk-line handling of air- or moisture-sensitive compounds. It is commonly employed as a round-bottom flask, ground-joint flask, distillation flask or dedicated receiving flask in research and quality-control laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask Schlenk 100 ml ST 14/23 straight
What is this article?
Collecting flask Schlenk 100 ml ST 14/23 straight is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Laborbedarf.
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.
