Description
Schlenk flask 1000 ml with socket NS 29/32 and lateral high-vacuum PTFE valve (fine thread) is laboratory glassware for inert-atmosphere and vacuum work. Made from borosilicate glass 3.3, it provides the chemical resistance and thermal stability needed for synthetic chemistry. The side-mounted HV PTFE valve uses a fine-thread mechanism with an adjustable passage of 0–10 mm, and the olive has a diameter of 9 mm for secure tubing connection. Nominal volume is 1 l and the ground joint size is NS 29/32, so the flask couples directly to standard Schlenk lines and vacuum manifolds. This vessel from manufacturer Rettberg supports evacuation, inert-gas blanketing and transfer steps typical of air-sensitive and organometallic reactions. Supplied as a single piece with a net weight of 0,335 kg, it suits preparative organic synthesis and other applications that demand reliable high-vacuum sealing and repeated thermal cycling within established Schlenk apparatus setups in research and teaching laboratories.
This article belongs on Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 1000 ml, socket size 29/32, PTFE high vacuum-valve
What is this article?
Nitrogen flask, 1000 ml, socket size 29/32, PTFE high vacuum-valve is the article on this page. Luminix Health distributes Rettberg 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.
