Description
Two-neck round-bottom flask in borosilicate glass with centre neck NS 29/32 and parallel side arm NS 19/26 offers a 1000 ml working volume for distillation, reaction and collection procedures. Produced from heat-resistant, durable borosilicate glass conforming to DIN 12394 and DIN 12392, the vessel combines a thick wall, heavy base and reinforced rim to help withstand handling during cleaning and transport. Precisely ground NS necks with a smooth interior ensure a secure, leak-tight seal with compatible ground-joint glassware. White enamel markings provide lasting, easy-to-read identification. This two-neck configuration from manufacturer ISOLAB Laborgeräte supports synthetic work, solvent recovery and multi-port setups that benefit from a parallel side arm. The round-bottom form aids uniform heating and stirring, while the dual standard joints permit concurrent attachment of condensers, addition funnels, gas lines or receivers. Suitable for distillation trains, reflux assemblies and laboratory receiving duties, the flask is supplied as one piece for straightforward integration into existing ground-joint systems.
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 29/32 -
What is this article?
flask - round bottom - two neck - parallel side arm - center neck : NS 29/32 - 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.
