Description
Round-bottom flask, narrow neck, with volume marking and frosted label area in Boro 3.3 is a laboratory boiling flask supplied with white inscription and a nominal volume of 10000 ml. Manufactured to DIN ISO 1773, the vessel combines a classic round-bottom geometry with a narrow neck for controlled handling of liquids during heating, distillation and general preparative work. The clear volume marking supports quick visual checks of fill level, while the frosted label area provides a durable writing surface for sample identification without additional tags. Borosilicate glass 3.3 offers the thermal and chemical resistance expected of routine laboratory glassware. This configuration from manufacturer Hecht is intended for everyday use on the bench or in heating baths where a stable, well-marked flask is required. Each unit is supplied as a single piece, ready for integration into standard laboratory glassware sets. The white inscription remains legible under typical lab lighting and cleaning regimes, helping maintain clear identification throughout repeated use cycles.
This article is part of Round-bottom flasks, in Beakers & flasks.

What is this article?
Flasks, boiling, round bottom, narrow neck, DIN 1773, Boro 3.3, printing white, is the article on this page. Luminix Health distributes Hecht 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.
