Description
Nitrogen Schlenk flask, 2000 ml, socket NS 29/32, lateral PTFE valve 0-3 mm is a precision laboratory vessel for inert-gas and vacuum work in synthetic chemistry. Manufactured from borosilicate glass 3.3, the flask features a single neck with standard ground socket NS 29/32 and a lateral PTFE valve adjustable from 0 to 3 mm together with an 8 mm olive for secure tubing connection. The nominal volume of 2 l supports larger-scale Schlenk techniques such as solvent drying, reagent transfer under nitrogen, and air-sensitive reactions. With a net weight of 0,550 kg the robust construction ensures stability on the bench while remaining compatible with common laboratory stands and clamps. This Schlenk apparatus item from manufacturer Rettberg is supplied as a single piece and belongs to the established range of Schlenk flasks used in research and teaching laboratories. The combination of high-quality glass, precise joint dimensions and reliable PTFE valve control makes the flask suitable for repeated evacuation and back-filling cycles without compromising seal integrity.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 2000 ml, socket size 29/32,
What is this article?
Nitrogen flask, 2000 ml, socket size 29/32, is the article on this page. Luminix Health distributes Rettberg 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.
