Beschreibung
Schlenk receiving flask 25 ml with NS 14/23 joint is a compact round laboratory vessel for collecting small distillate fractions and managing air-sensitive samples under inert gas. It is equipped with a straight angle valve stopcock of the Economy type fitted with a PTFE spindle, a 3 mm bore and a lateral 8 mm olive for secure tubing attachment. The configuration supports controlled vacuum or inert-gas connections typical of Schlenk-line and microscale synthetic work. Fabricated from borosilicate glass 3.3 by manufacturer Witeg, the flask provides the chemical resistance and thermal performance required in routine laboratory use. Its 25 ml capacity and low net weight of 0,032 kg make it especially suitable for small-scale organic synthesis, solvent recovery and preparative receiving steps. The round-bottom shape aids uniform heating and efficient mixing with appropriate laboratory heaters. This receiving flask integrates easily into existing NS 14/23 ground-joint systems used for distillation and air-free manipulations in research and teaching laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask Schlenk 25 ml ST 14/23 straight
What is this article?
Collecting flask Schlenk 25 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.
