Description
Receiving flask according to Schlenk, 25 ml cylindrical, with NS 14/23 socket is a laboratory vessel designed for distillation receivers and air-sensitive handling. It features a round bottom, cylindrical body, nominal volume of 25 ml (0,025 l) and an NS 14/23 ground joint sleeve. A lateral stopcock NS 14,5 with an 8 mm olive, hollow plug and 2,5 mm bore provides a convenient side connection for vacuum or inert gas. Dimensions are 120 × 32 mm. From manufacturer Witeg, the flask is supplied as one piece with a net weight of 0,081 kg and originates from Germany. The standardised NS 14/23 joint integrates smoothly with condensers, distillation heads and Schlenk manifolds, while the side arm supports evacuation, back-filling or controlled transfer. The cylindrical profile offers a practical footprint for heating baths, cold traps and bench setups. Suitable for organic synthesis, preparative work-up and small-scale vacuum distillations, this Schlenk-type receiving flask delivers reliable ground-joint performance and side-arm control for everyday laboratory use.
This article belongs on Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Collecting flask cylindrical 25 ml ST 14
What is this article?
Collecting flask cylindrical 25 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 Matériel de laboratoire.
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.
