Description
Nitrogen round-bottom flask with NS 14/23 joint and angled side arm with PTFE stopcock is a 25 ml Schlenk-type vessel made from heat-resistant, durable borosilicate glass conforming to DIN and ISO standards. The side arm carries a PTFE stopcock set at a 25° angle, supporting controlled inert-gas or vacuum work in air-sensitive chemistry. A thick wall, heavy base and reinforced rim reduce the risk of breakage during cleaning and transport, while perfectly ground NS necks with a smooth interior provide a reliable, leak-tight seal. Volume graduations and markings are printed in durable white enamel for clear readability at the bench. Supplied as a single piece from manufacturer ISOLAB Laborgeräte, this flask suits routine Schlenk-line operations, solvent handling under inert atmosphere and small-scale synthetic work where thermal stability and mechanical robustness are required. The compact 25 ml capacity is well matched to micro- and semi-micro preparations.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flasks - round bottom - for nitrogen - socket : NS 14/23 - 25 ml
What is this article?
flasks - round bottom - for nitrogen - socket : NS 14/23 - 25 ml is the article on this page. Luminix Health distributes ISOLAB 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.
