Description
Round-bottom flask 500 ml NS 29/32 amber is a single-neck laboratory flask designed for distillation, collection and general processing of light-sensitive chemicals. Produced from borosilicate glass 3.3, it offers a medium neck with ground joint NS 29/32 and an integral brown tint that attenuates light reaching the contents. Outer diameter is 105 mm and height 170 mm, yielding a 500 ml nominal volume suited to larger heating mantles and standard laboratory supports. Because the amber colouration is built into the glass, light protection remains consistent after repeated heating, cooling and cleaning cycles. These flasks from manufacturer Witeg come in packs of 10 pieces and are appropriate for organic synthesis, solvent recovery, receiving applications and temporary storage of photosensitive reagents. Borosilicate 3.3 supplies the thermal-shock resistance and chemical durability expected in research and quality-control environments. Net weight is 0,167 kg per flask. The single medium neck simplifies assembly with condensers, adapters and stoppers, while the NS 29/32 joint ensures reliable interchangeability within common laboratory glassware systems.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 500 ml ST 29/32 amber stained
What is this article?
Round bottom flask 500 ml ST 29/32 amber stained is the article on this page. Luminix Health distributes Witeg 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.
