Description
Schlenk flask, 25 ml, equipped with socket NS 14,5/23 and a lateral PTFE valve (bore 0–3 mm) plus 8 mm olive, is compact laboratory glassware designed for inert-atmosphere and vacuum operations. Constructed from borosilicate glass 3.3, the flask supports air-sensitive synthesis, small-scale reactions and temporary storage on Schlenk lines. The nominal volume of 25 ml is well suited to micro- and semi-micro work, while the ground joint NS 14,5/23 ensures leak-tight connection to standard apparatus. The side-mounted PTFE valve allows precise regulation of gas flow or vacuum, and the 8 mm olive provides a reliable tubing interface. Supplied by manufacturer Rettberg, this single-neck Schlenk flask benefits from the excellent chemical resistance and thermal properties of borosilicate glass 3.3. It is particularly useful in organometallic chemistry, catalyst screening and other applications that demand rigorous exclusion of air and moisture. Net weight is only 0,038 kg, facilitating easy handling on vacuum manifolds and laboratory benches.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Nitrogen flask, 25 ml, socket size 14,5/23, side PTFE-valve 0 - 3 mm,
What is this article?
Nitrogen flask, 25 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.
