Description
Flat-bottom flask 50 ml narrow neck BORO 3.3 is a medium-length laboratory standing flask made from borosilicate glass 3.3, designed for routine preparation, heating and holding of liquid samples on a stable base. With a nominal volume of 50 ml (0,05 l), the vessel features a beaded rim and a narrow neck that supports controlled pouring and secure stopper or stopper-compatible closures. External dimensions include a flask diameter of 51 mm, an overall height of 100 mm and a neck diameter of 22 mm, giving a compact footprint suitable for water baths, hotplates and standard laboratory racks.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.
The borosilicate glass 3.3 construction offers the thermal and chemical resistance expected of everyday lab glassware for aqueous media, solvents and mild reagents. Supplied in packs of 10 pieces from manufacturer Witeg, these Enghals flat-bottom flasks are practical consumables for teaching laboratories, quality-control benches and general analytical workflows where a stable standing form is preferred over round-bottom geometry. Net weight is approximately 0,055 kg per flask. The clear glass body allows easy visual inspection of contents and fill level during weighing, mixing or temporary storage of process intermediates.

Questions about Flasks, flat bottom, medium length, 50 m
What is this article?
Flasks, flat bottom, medium length, 50 m 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.
