Description
Evaporating flask 2000 ml NS 29/32 coated is a pear-shaped clear-glass vessel designed for rotary evaporators and related distillation or concentration work. Produced from borosilicate glass 3.3, it features a standard ground joint NS 29/32, an outer diameter of 160 mm and a height of 235 mm for a nominal volume of 2 l. An exterior plastic coating supplies an extra safety barrier that helps retain contents in the event of breakage while keeping the interior fully visible. This evaporating flask from manufacturer Witeg supports solvent recovery, sample concentration and preparative workflows in chemical, pharmaceutical and research laboratories. The borosilicate glass 3.3 construction offers reliable chemical resistance and thermal-shock behaviour for everyday laboratory use. Each flask weighs 0,527 kg net and is supplied in packs of 10 pieces. The pear geometry aids efficient swirling and heat exchange during vacuum rotation.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Evaporating flask 2000 ml ST 29/32 plastic coated
What is this article?
Evaporating flask 2000 ml ST 29/32 plastic coated is the article on this page. Luminix Health distributes Witeg 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.
