Description
Evaporating flask, DURAN®, pear-shaped is a laboratory glass vessel for concentration and solvent-removal work on a rotary evaporator or related apparatus. This 100 ml flask features a standard ground joint 29/32 for secure, interchangeable connection to common evaporator assemblies and glassware trains. The pear-shaped profile promotes efficient film formation and mixing of the contents during rotation, supporting controlled evaporation of solutions in organic synthesis, sample work-up and preparative chemistry. Manufactured from DURAN® borosilicate glass, the flask offers the chemical resistance and thermal performance expected in routine laboratory evaporation tasks. It is supplied as one piece with a weight of 0,065 kg, making it convenient for frequent change-over between samples. This evaporating flask from manufacturer Lenz integrates into standard ranges of round flasks and flasks with ground glass joints used across research and analytical laboratories. The NS 29/32 joint ensures compatibility with widely used taper connections, while the compact 100 ml working volume suits small-batch concentration, solvent exchange and related process steps where reliable glassware geometry matters.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Evaporating flask, DURAN®, pear-shaped, with standard ground joint 29/32, 100 ml
What is this article?
Evaporating flask, DURAN®, pear-shaped, with standard ground joint 29/32, 100 ml is the article on this page. Luminix Health distributes Lenz 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.
