Description
Round-bottom flask, narrow neck, with volume marking and frosted label area in Boro 3.3 is a 100 ml laboratory vessel intended for heating, boiling and general reaction procedures. It features a white inscription, a clear volume marking and a frosted matt label area that allows durable sample identification without adhesive labels. Manufactured from borosilicate glass 3.3 in accordance with DIN ISO 1773, the flask combines thermal shock resistance with broad chemical durability for everyday laboratory service. The narrow neck facilitates secure stoppering, limits evaporation and integrates with standard clamps, heating mantles and rotary-evaporator setups. The spherical body supports uniform heat distribution during reflux, distillation or synthesis work. Offered as a pack of ten pieces from manufacturer Hecht, this format is practical for teaching laboratories, research groups and routine wet-chemistry environments that consume multiple identical flasks. The frosted shield accepts pencil or marker notes for clear, lasting identification. A reliable choice wherever a standardised 100 ml narrow-neck round-bottom flask in Boro 3.3 is required for consistent laboratory practice.
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.
