Description
Schlenk flask, 50 ml, featuring socket NS 14,5/23, a lateral PTFE valve with bore 0–3 mm and an 8 mm olive, is versatile laboratory glassware for handling air-sensitive compounds under inert gas or vacuum. Made from borosilicate glass 3.3, the flask is intended for Schlenk-line techniques, small-scale synthesis, distillations and temporary storage. The 50 ml nominal volume balances working capacity with compact dimensions, while the precision ground joint NS 14,5/23 ensures compatibility with common laboratory connectors. The side-mounted PTFE valve enables fine control of gas admission or evacuation, and the integrated 8 mm olive offers a secure tubing connection. This apparatus from manufacturer Rettberg utilises the proven chemical resistance and thermal shock durability of borosilicate glass 3.3. It is well suited to organometallic chemistry, catalysis research and other applications requiring strict exclusion of air and moisture. With a net weight of 0,044 kg the flask remains easy to manipulate on manifolds and in fume hoods, providing a reliable tool for professional 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 14,5/23, side PTFE-valve 0 - 3 mm,
What is this article?
Nitrogen flask, 50 ml, socket size 14,5/23, side PTFE-valve 0 - 3 mm, 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.
