Description
Two-neck round-bottom flask with centre neck NS 24/29 and parallel side arm NS 14/23 is a 1000 ml borosilicate glass vessel for distillation, reaction and collection work. Manufactured from heat-resistant, durable borosilicate glass to DIN 12394 and DIN 12392, it combines a thick wall, heavy base and reinforced rim that reduce the risk of breakage during cleaning and transport. Perfectly ground NS necks with a smooth interior provide a reliable, leak-tight seal when mated with standard taper joints. White enamel markings remain clearly legible on the bench. The parallel side-neck geometry supports compact multi-joint assemblies such as condensers, dropping funnels or gas inlets alongside the main centre neck. Offered as a single piece from manufacturer ISOLAB Laborgeräte, this flask fits routine synthetic and analytical workflows that require simultaneous access through two ground joints. Suitable for use as a round-bottom, ground-joint, distillation or receiving flask in teaching and research laboratories where mechanical robustness and standard joint compatibility are essential.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - round bottom - two neck - parallel side arm - center neck : NS 24/29 -
What is this article?
flask - round bottom - two neck - parallel side arm - center neck : NS 24/29 - 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.
