Description
Round-bottom flask 100 ml NS 29/32 amber is a single-neck laboratory vessel intended for distillation, collection and general chemical handling of light-sensitive media. Made from borosilicate glass 3.3, it combines a medium neck with a precision ground joint NS 29/32 and an integral brown tint that reduces light transmission to the contents. Outer diameter is 64 mm and overall height is 110 mm, giving a compact 100 ml nominal volume that fits standard heating mantles, clamps and stands. The amber colouration is part of the glass itself, so protection remains stable through repeated thermal cycles and cleaning. These flasks from manufacturer Witeg are packed in units of 10 pieces and suit organic synthesis, solvent recovery, receiving duties and short-term storage of photosensitive reagents. Borosilicate 3.3 provides the thermal-shock resistance and chemical durability expected in research and quality-control work. Net weight is 0,067 kg per flask. The single medium neck simplifies connection to condensers, adapters and stoppers while maintaining a reliable seal at the NS 29/32 joint for routine laboratory assemblies.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 100 ml ST 29/32 amber stained
What is this article?
Round bottom flask 100 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 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.
