Description
Evaporating flask 250 ml NS 29/32 is a pear-shaped laboratory flask for rotary evaporation and related concentration work. It is manufactured from heat-resistant, durable borosilicate glass according to DIN standard 12383, providing the thermal and mechanical stability expected in routine laboratory glassware. The thick wall, heavy base and reinforced rim help prevent breakage during cleaning and transport. Perfectly ground NS 29/32 necks with a smooth interior guarantee a leak-proof seal when connected to rotary evaporators or other standard taper apparatus. Markings are printed in white enamel for clear, durable identification that remains legible after repeated washing. Supplied as a single piece, this 250 ml flask from manufacturer ISOLAB Laborgeräte suits sample concentration, solvent recovery and preparative workflows in chemical, pharmaceutical and research laboratories. The pear-shaped (Birnenkolben) geometry is the established form for evaporating flasks, supporting even liquid distribution during rotation. Laboratories requiring robust DIN 12383 borosilicate evaporating flasks with NS 29/32 joints will find this unit a practical choice for everyday vacuum evaporation tasks.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - evaporating - NS 29/32 - 250 ml
What is this article?
flask - evaporating - 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.
