Description
Three-neck round-bottom flask with centre neck NS 14/23 and two angled side arms NS 14/23 is a 250 ml laboratory vessel produced from heat-resistant, durable borosilicate glass in accordance with DIN 12394. The thick wall, heavy base and reinforced rim minimise breakage risk during cleaning and handling, while perfectly ground NS necks with a smooth interior ensure a reliable, leak-tight seal with compatible ground-joint accessories. White enamel markings give clear, permanent identification on the bench. The two angled side arms, together with the centre neck, allow simultaneous connection of condensers, dropping funnels, stirrers or probes, supporting compact multi-component reaction, distillation and collection setups. This 250 ml flask from manufacturer ISOLAB Laborgeräte combines mechanical durability with the chemical resistance typical of quality borosilicate glassware. Supplied as a single piece, it is well suited to research, teaching and routine laboratory work requiring versatile three-neck round-bottom glassware in a convenient smaller volume.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - round bottom - three neck - angled side arm - center neck : NS 14/23 -
What is this article?
flask - round bottom - three neck - angled side arm - center neck : NS 14/23 - 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.
