Description
Evaporating flask with PUR coating is a pear-shaped laboratory vessel made from DURAN® glass, equipped with a ground joint NS 29/32 and a nominal capacity of 50 ml. Intended for rotary evaporation, solvent removal and related concentration work, the pear-shaped body supports even liquid-film distribution during rotation under reduced pressure. An outer polyurethane (PUR) coating provides an additional protective layer that can help retain glass fragments if the flask is accidentally damaged, improving handling safety in busy laboratory environments. This single-unit flask from manufacturer Lenz weighs 0,053 kg and fits standard evaporators and glassware trains that accept NS 29/32 joints. DURAN® glass offers the thermal and chemical durability expected of routine laboratory borosilicate ware, while the PUR coating complements the base material for workflows where mechanical protection is valued. Suitable for chemical, pharmaceutical and life-science sample preparation, the flask belongs to the established range of jointed evaporating and round flasks used for distillation and concentration tasks. Pack size is one piece, ready for immediate integration into existing rotary-evaporator setups.
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, 50ml, 1 unit(s)
What is this article?
Evaporating flask with PUR coating, DURAN®, pear-shaped, 29/32, 50ml, 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.
