Description
Flat-bottom flask 100 ml narrow neck BORO 3.3 is a medium-length standing flask in borosilicate glass 3.3 intended for general laboratory preparation, gentle heating and short-term holding of liquids. The 100 ml (0,1 l) nominal capacity is paired with a narrow Enghals neck and beaded rim, which aid controlled pouring and compatibility with common laboratory stoppers. Key dimensions are a flask diameter of 64 mm, overall height of 110 mm and neck diameter of 22 mm, providing a stable base for use on hotplates, water baths and standard racks without the need for a cork ring.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.
Borosilicate glass 3.3 delivers the chemical and thermal performance expected for routine aqueous and solvent work in teaching, quality-control and research environments. Supplied as a pack of 10 pieces from manufacturer Witeg, these BORO 3.3 flat-bottom flasks are practical glassware for workflows that benefit from a free-standing geometry rather than round-bottom forms. Net weight is approximately 0,06 kg per flask. The transparent body supports clear visual monitoring of fill level, mixing and any visible changes during sample handling or intermediate storage on the bench.

Questions about Flasks, flat bottom, medium length, 100
What is this article?
Flasks, flat bottom, medium length, 100 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.
