Description
Three-neck round-bottom flask with centre neck NS 24/29 and two parallel side arms NS 19/26, 1000 ml is a multi-port laboratory vessel designed for larger-scale distillation, synthesis and reaction assemblies. Fabricated from heat-resistant, durable borosilicate glass according to DIN 12394, it incorporates a thick wall, heavy base and reinforced rim that minimise breakage risk during cleaning and handling. Perfectly ground standard-taper necks with smooth interiors ensure a reliable, leak-tight seal with matching ground-glass joints. Permanent white enamel markings give clear vessel identification. Parallel side arms enable simultaneous connection of condensers, dropping funnels or gas lines while the centre neck remains free for stirring or temperature control. Available as a single piece from manufacturer ISOLAB Laborgeräte, this 1000 ml flask is well suited to preparative organic chemistry, process development and multi-component workflows that demand stable joint geometry and thermal durability. Its sturdy build and standardised NS joints support everyday laboratory use under thermal and mechanical stress.
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 24/29 -
What is this article?
flask - round bottom - three 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.
