Description
Evaporating flask, DURAN®, pear-shaped is a laboratory glass vessel intended for concentration and solvent-removal workflows. This pear-shaped flask carries a standard ground joint NS 29/32 and a nominal capacity of 50 ml, making it appropriate for small-scale rotary evaporation where a larger joint size is preferred. Fabricated from DURAN® glass, it delivers the chemical resistance and thermal stability required in daily laboratory practice. The pear form promotes efficient liquid-film distribution and straightforward recovery of residues after reduced-pressure evaporation. Delivered as a single piece weighing 0,052 kg, the flask integrates with compatible NS 29/32 condensers, adapters and rotary evaporator setups. This version from manufacturer Lenz belongs to the familiar range of round flasks and flasks with ground glass joints used across analytical, synthetic and preparative labs. The standard ground joint ensures a reliable, interchangeable seal to jointed apparatus. Transparent pear-shaped walls support visual process control and easy sample handling. Select this 50 ml DURAN® evaporating flask when compact volume and NS 29/32 connectivity are needed for routine evaporation tasks.
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, 50ml
What is this article?
Evaporating flask, DURAN®, pear-shaped, with standard ground joint 29/32, 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.
