Description
Evaporating flask 1000 ml NS 29/32 is a pear-shaped laboratory flask designed for rotary evaporation and larger-scale concentration work. It is produced from heat-resistant, durable borosilicate glass according to DIN standard 12383, combining thermal stability with mechanical robustness for daily laboratory cycles. 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 fitted to rotary evaporators or compatible ground-joint apparatus. Markings printed in white enamel ensure clear, durable identification that withstands repeated washing. Supplied as one piece, this 1000 ml flask from manufacturer ISOLAB Laborgeräte is appropriate for concentration of larger sample volumes, solvent recovery and preparative workflows in chemical, life-science and pharmaceutical laboratories. The pear-shaped (Birnenkolben) form is the established geometry for evaporating flasks and supports even distribution of the liquid film during rotation under reduced pressure. Laboratories requiring sturdy DIN 12383 borosilicate evaporating flasks with NS 29/32 joints will find this litre-scale unit a practical choice for routine 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 - 1000 ml
What is this article?
flask - evaporating - NS 29/32 - 1000 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.
