Description
Two-neck round-bottom flask with centre neck NS 29/32 and parallel side arm NS 14/23 is a 2000 ml borosilicate glass vessel designed for distillation, synthesis and collection work. Manufactured from heat-resistant, durable borosilicate glass in accordance with DIN 12394 and DIN 12392, it features 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 guarantee a leak-tight seal when mated with standard taper joints. Clear white enamel markings aid identification in busy laboratory environments. This flask from manufacturer ISOLAB Laborgeräte offers a practical parallel side-neck geometry that simplifies the attachment of condensers, addition funnels or probes alongside the main centre neck. Ideal for organic reactions, solvent recovery and receiving applications, the 2000 ml capacity suits medium-scale preparative work. The robust construction and precise ground joints make it a reliable component in multi-neck apparatus setups used across research, teaching and industrial quality-control laboratories.
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.
