Description
Evaporating flask, DURAN®, pear-shaped is a laboratory evaporating vessel with a standard ground joint 14/23 and a nominal capacity of 10 ml. Its pear-shaped profile is suited to solvent evaporation, concentration steps and small-batch work where residual sample collects efficiently in the lower bulb. Fabricated from DURAN® glass, the flask is intended for use in modular ground-joint apparatus typical of organic chemistry, analytical sample preparation and educational laboratories. The NS 14/23 joint provides a standardised interface to rotary evaporators, condensers and other 14/23 components without intermediate adapters. Supplied as a single piece weighing 0,046 kg, it is practical for dedicated small-volume lines or as a matched spare. This evaporating flask from manufacturer Lenz forms part of the broader range of round flasks and ground-joint glassware used in distillation and extraction setups. The 10 ml capacity bridges micro-scale and intermediate volumes while retaining the compact pear geometry preferred for controlled evaporation. Laboratories that rely on DURAN® joint systems can integrate the flask directly into existing trains for reproducible assembly and clear visual monitoring of the contents during heating or reduced-pressure work.
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 14/23, 10ml
What is this article?
Evaporating flask, DURAN®, pear-shaped, with standard ground joint 14/23, 10ml 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.
