Description
Round-bottom flask 100 ml with NS 24/29 ground joint is a brown-stained laboratory vessel manufactured from borosilicate glass 3.3. The flask features a single centre neck and is intended for distillation, reflux and general reaction work where light-sensitive media need protection from ambient light. External diameter measures 64 mm and overall height is 110 mm, providing a stable footprint on heating mantles, oil baths and laboratory stands. Brown staining reduces UV and visible light transmission, helping to protect photosensitive compounds during storage or processing. From manufacturer Witeg, the flask offers the chemical resistance and thermal stability associated with borosilicate glass 3.3 together with a standard NS 24/29 joint for compatibility with common condensers, adapters and other ground glassware. Nominal volume is 100 ml (0,1 l). Supplied in packs of 10 pieces, these flasks suit routine synthetic and analytical workflows in research and quality-control laboratories handling light-sensitive reagents.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 100 ml ST 24/29 amber stained
What is this article?
Round bottom flask 100 ml ST 24/29 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 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.
