Beschrijving
Schlenk flask 1000 ml NS 29/32 is a round-bottom laboratory vessel intended for air-sensitive synthesis, inert-gas handling and vacuum work. Made from borosilicate glass 3.3, it combines a standard ground joint NS 29/32 with a lateral stopcock angled at 45° and fitted with a solid plug. The hose connection is 8 mm with a 2,5 mm bore, allowing secure attachment to vacuum or inert-gas lines typical of Schlenk technique. The 1000 ml working volume suits larger preparative reactions, solvent transfers, distillations and temporary storage of reactive intermediates under controlled atmosphere. Categories such as round-bottom flasks, ground-joint flasks and receiving flasks reflect its versatile role in organic and inorganic laboratories. Offered as a single piece from manufacturer Witeg, the flask provides the chemical resistance and thermal stability expected of borosilicate glass 3.3 for routine bench and manifold work. Net weight is approximately 0,308 kg, making it practical for standard laboratory stands and clamps while remaining robust enough for repeated use in synthetic workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask (Schlenk), round bottom,
What is this article?
Nitrogen flask (Schlenk), round bottom, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Rondbodemkolven, inside Bekerglazen & kolven, in Labmateriaal.
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.
