Description
Nitrogen round-bottom flask NS 29/32 with angled side arm and PTFE stopcock, 250 ml is a larger Schlenk-type round-bottom flask for inert-atmosphere chemistry and vacuum work. It is made from heat-resistant, durable borosilicate glass meeting DIN and ISO standards and features a side arm angled at 25° with an integrated PTFE stopcock for controlled connection to gas or vacuum systems. Thick walls, a heavy base and a reinforced rim help prevent breakage during cleaning and transport. Perfectly ground NS 29/32 necks with a smooth interior ensure a dependable, leak-tight seal. Quantity markings and inscriptions are printed in white enamel for lasting clarity. Supplied as a single unit from manufacturer ISOLAB Laborgeräte, this 250 ml flask is suited to Schlenk-line setups, larger-scale solvent transfers under inert gas and synthetic operations requiring a secure nitrogen or vacuum port. Robust construction makes it a practical choice for repeated use in organic, inorganic and materials laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flasks - round bottom - for nitrogen - socket : NS 29/32 - 250 ml
What is this article?
flasks - round bottom - for nitrogen - socket : NS 29/32 - 250 ml 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.
