Description
Three-neck round-bottom flask with centre neck NS 29/32 and two parallel side arms NS 14/23 is a 1000 ml borosilicate glass vessel designed for multi-port reaction, distillation and collection work. Manufactured from heat-resistant, durable borosilicate glass in accordance with DIN 12394, it features thick walls, a heavy base and a reinforced rim that reduce the risk of breakage during cleaning and transport. The perfectly ground standard taper necks have a smooth interior to ensure a reliable, leak-tight seal with matching ground-joint glassware. Parallel side necks allow convenient attachment of condensers, dropping funnels or thermometers without crowding the centre joint. White enamel markings provide clear, durable identification of capacity and joint sizes. This flask from manufacturer ISOLAB Laborgeräte is supplied as a single piece and suits routine organic synthesis, solvent recovery and multi-component setups where simultaneous addition, stirring and vapour take-off are required. The robust construction and precise ground joints make it a practical choice for teaching and research laboratories handling moderate volumes.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - round bottom - three neck - parallel side arm - center neck : NS 29/32 -
What is this article?
flask - round bottom - three 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 Ballons à fond rond, inside Béchers & fioles, in Matériel de laboratoire.
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.
