Description
Two-neck round-bottom flask with centre neck NS 29/32 and angled side arm NS 29/32, capacity 1000 ml, is manufactured from heat-resistant, durable borosilicate glass conforming to DIN 12394 and DIN 12392. This laboratory flask serves distillation, reaction and collection tasks that require two standard ground joints on one vessel. A thick wall, heavy base and reinforced rim reduce the risk of breakage during cleaning and transport, supporting repeated use in busy laboratories. Perfectly ground NS necks with a smooth interior deliver a secure, leak-tight seal when paired with matching glassware. White enamel markings provide clear, lasting identification. Supplied as a single unit from manufacturer ISOLAB Laborgeräte, the flask works well in organic synthesis lines, multi-neck reaction assemblies and larger receiver setups. The standardised NS 29/32 joints accept common condensers, dropping funnels and adapters, making it a dependable choice for teaching laboratories, research groups and process development needing robust borosilicate glassware.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - round bottom - two neck - angled side arm - center neck : NS 29/32 -
What is this article?
flask - round bottom - two neck - angled 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.
