Description
Nitrogen round-bottom flask with NS 14/23 joint and angled side arm with PTFE stopcock is a 50 ml Schlenk-type vessel manufactured from heat-resistant, durable borosilicate glass according to DIN and ISO standards. It features a PTFE stopcock on a side arm angled at 25°, enabling convenient connection to inert-gas or vacuum lines for air-sensitive reactions. Thick walls, a heavy base and a reinforced rim help prevent breakage during cleaning and transport. Perfectly ground NS necks with a smooth interior ensure a secure, leak-tight seal under routine laboratory conditions. Volume graduations and inscriptions are applied in white enamel for lasting visibility. Offered as one piece from manufacturer ISOLAB Laborgeräte, the flask is intended for Schlenk techniques, solvent transfers under protective atmosphere and general synthetic work that demands thermal and mechanical reliability. The 50 ml working volume balances sample size with ease of handling on the bench or manifold.
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 14/23 - 50 ml
What is this article?
flasks - round bottom - for nitrogen - socket : NS 14/23 - 50 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.
