Description
Evaporating flask 50 ml NS 29/32 is a compact pear-shaped vessel offering a nominal volume of 0,05 l together with a standard ground joint NS 29/32. Produced from borosilicate glass 3.3 as uncoated clear glass, it combines chemical resistance with good thermal shock tolerance for everyday laboratory evaporation tasks. External diameter is 51 mm and overall height is 90 mm, giving a conveniently small footprint on rotary evaporators and distillation assemblies. Supplied in packs of 10 pc(s) with a net weight of 0,055 kg per flask, the item originates from manufacturer Witeg. The pear profile aids smooth film formation and efficient solvent recovery under reduced pressure, while the clear glass walls allow direct visual monitoring of the sample. The NS 29/32 joint ensures leak-free connection to standard laboratory glassware. Ideal for small-scale concentration, solvent exchange and sample work-up in organic chemistry, analytical and teaching laboratories, this uncoated flask is easy to clean and inspect between uses and retains dimensional accuracy at the ground joint under normal operating conditions.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Evaporating flask 50 ml ST 29/32
What is this article?
Evaporating flask 50 ml ST 29/32 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.
