Description
Round-bottom flask 100 ml narrow neck borosilicate glass is a single-neck laboratory flask made from borosilicate glass 3.3 for heating, distillation, reflux and general reaction work. The nominal volume is 0,1 l. Geometry is medium-length with a beaded rim: flask diameter 64 mm, overall height 115 mm and neck diameter 22 mm. The Enghals (narrow-neck) design limits evaporative losses and supports controlled vapour paths when stoppers or simple adapters are fitted.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.
Supplied in packs of 10 pieces from manufacturer Witeg, the flask is suited to organic synthesis, solvent recovery, concentration steps and teaching laboratories. Borosilicate glass 3.3 provides the thermal-shock resistance and chemical durability expected for aqueous media and many organic solvents on heating mantles or oil baths. The one-neck layout keeps setups compact for single-inlet operations, while the beaded rim strengthens the mouth for repeated handling and clamping.
Typical placements include round-bottom, distillation and collection-flask workflows where a clear 100 ml working volume and stable spherical body are required. Dimensions and material grade follow the stated manufacturer data so the vessel can be matched consistently with standard laboratory glassware accessories and heating equipment.

Questions about Flasks round bottom 100 ml narrow neck boro
What is this article?
Flasks round bottom 100 ml narrow neck boro 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.
