Description
Nitrogen round-bottom flask with NS 14/23 joint and angled side arm with PTFE stopcock is a 100 ml Schlenk-type vessel produced from heat-resistant, durable borosilicate glass in accordance with DIN and ISO standards. The side arm is fitted with a PTFE stopcock angled at 25°, facilitating inert-gas blanketing or vacuum operations in air-sensitive chemistry. A thick wall, heavy base and reinforced rim minimise breakage risk during cleaning and transport, while perfectly ground NS necks with a smooth interior deliver a dependable leak-tight seal. Quantity graduations and markings are printed in white enamel for clear, long-lasting readability. Available as a single unit from manufacturer ISOLAB Laborgeräte, this flask supports Schlenk-line workflows, solvent handling under protective atmosphere and medium-scale synthetic preparations that require thermal stability and mechanical strength. The 100 ml capacity offers a practical working volume for everyday laboratory use on the manifold or bench.
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 - 100 ml
What is this article?
flasks - round bottom - for nitrogen - socket : NS 14/23 - 100 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.
