Description
Evaporating flask, DURAN®, pear-shaped is a laboratory glass vessel for solvent removal and sample concentration. This pear-shaped flask is fitted with a standard ground joint NS 14/23 and offers a nominal capacity of 50 ml, suited to compact rotary-evaporation and related preparative work. Made from DURAN® glass, it provides the chemical and thermal performance expected of everyday jointed labware. The pear geometry supports even film formation on the wall and practical recovery of residues after evaporation under reduced pressure. Supplied as one piece with a weight of 0,049 kg, the flask couples readily to matching ground-joint condensers, adapters and rotary evaporator assemblies. This model from manufacturer Lenz sits within the established family of round flasks and flasks with ground glass joints used in analytical, synthetic and preparative laboratories. The NS 14/23 joint gives a secure, interchangeable connection to standard apparatus trains. Clear pear contours aid visual monitoring of the process liquid and simplify transfer of concentrated samples. Choose this 50 ml DURAN® evaporating flask when a small working volume and NS 14/23 connectivity are required for routine evaporation duties.
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, 50ml
What is this article?
Evaporating flask, DURAN®, pear-shaped, with standard ground joint 14/23, 50ml is the article on this page. Luminix Health distributes Lenz for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Matériel de laboratoire.
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.
