Description
Schlenk flask, 50 ml, with socket NS 29/32 and lateral high-vacuum PTFE valve (fine thread) is compact laboratory glassware intended for air-sensitive and vacuum chemistry on a smaller scale. Made from borosilicate glass 3.3, it delivers the chemical resistance and thermal stability needed for Schlenk techniques, inert-gas manipulations and low-volume vacuum transfers. The lateral high-vacuum PTFE valve is equipped with a fine thread for precise control and provides an adjustable passage of 0–8 mm; the olive has a diameter of Ø 9 mm for secure hose attachment. The larger NS 29/32 ground joint offers versatile connectivity to standard laboratory fittings, stoppers and adapters. Nominal capacity is 50 ml and net weight is 0,089 kg, making the flask convenient for screening reactions, catalyst tests and handling of limited sample quantities. This Schlenk flask from manufacturer Rettberg is supplied as one piece and supports reliable isolation of reactive media under vacuum or protective atmosphere. Its robust design and fine-thread valve geometry suit organometallic work, coordination chemistry and other moisture- or oxygen-sensitive procedures in research laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 50 ml, socket size 29/32, PTFE high vacuum-valve
What is this article?
Nitrogen flask, 50 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 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.
