Description
Flat-bottom flask, narrow neck, Boro 3.3 with white inscription to DIN ISO 1773 is a 4000 ml laboratory standing flask for everyday wet-chemistry work. The flat base gives stable placement on the bench, hotplate or heating mantle, while the narrow neck supports controlled filling, pouring, stoppering and connection to common laboratory fittings. Made from borosilicate glass 3.3, the vessel offers the chemical resistance and thermal behaviour expected of this glass type in heating, cooling and general solution handling. White inscription markings improve rapid identification of volume or content on busy benches and in shared glassware stores. Geometry follows DIN ISO 1773, supporting dimensional consistency and interchangeability with standard laboratory accessories. Supplied as one piece from manufacturer Hecht, this four-litre flask suits preparation, holding and processing of solutions, media and reagents in research, quality-control, production-support and teaching laboratories where a robust narrow-neck flat-bottom flask of 4000 ml capacity is required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

What is this article?
Flasks, boiling, flat 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.
