Description
Two-neck round-bottom flask with centre neck NS 29/32 and parallel side arm NS 29/32, 100 ml capacity, is a precision laboratory vessel made from heat-resistant, durable borosilicate glass conforming to DIN 12394 and DIN 12392. Intended for distillation, reaction and collection work, it combines a thick wall, heavy base and reinforced rim to reduce the risk of breakage during cleaning and transport. Perfectly ground standard taper necks with smooth interiors provide a reliable, leak-tight seal with matching ground-joint glassware. Clear white enamel markings support easy identification on the bench. Offered as a single piece from manufacturer ISOLAB Laborgeräte, this flask suits organic synthesis, solvent recovery and multi-port setups where a parallel side neck is preferred. Robust construction supports repeated thermal cycling typical of laboratory heating and cooling while preserving joint geometry and dimensional stability for consistent assembly of condensers, dropping funnels and other NS 29/32 accessories.
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.
