Description
Evaporating flask with PUR coating is a pear-shaped laboratory vessel made from DURAN® glass, fitted with a ground joint NS 29/32 and a nominal capacity of 100 ml. Designed for rotary evaporation, solvent concentration and related sample-preparation steps, the pear-shaped geometry promotes efficient film formation as the flask rotates under vacuum. The outer polyurethane (PUR) coating adds a protective layer that can help contain glass shards in the event of breakage, supporting safer handling during everyday laboratory use. Supplied as one piece from manufacturer Lenz, the flask weighs 0,082 kg and connects directly to evaporators and glassware assemblies that use NS 29/32 joints. DURAN® glass provides the chemical and thermal resistance expected in routine laboratory service, while the PUR coating extends mechanical protection for vacuum distillation and concentration workflows. This evaporating flask is appropriate for chemical, pharmaceutical and life-science laboratories that require reliable jointed glassware for solvent removal. The single-unit pack integrates readily into existing rotary-evaporator configurations without additional adapters for standard NS 29/32 systems.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Evaporating flask with PUR coating, DURAN®, pear-shaped, 29/32, 100ml, 1 unit(s)
What is this article?
Evaporating flask with PUR coating, DURAN®, pear-shaped, 29/32, 100ml, 1 unit(s) 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.
