Description
Flat-bottom flask in borosilicate glass 3.3 with standard ground joint NS 29/32, without stopper, 1000 ml is a standing laboratory flask for everyday chemical work. The vessel is made from borosilicate glass 3.3, a material chosen for its thermal shock resistance and chemical durability in routine lab environments. Its flat base allows stable placement on hotplates, magnetic stirrers and benchtops, while the NS 29/32 standard ground joint supports direct connection to condensers, adapters, drying tubes and other jointed glassware. No stopper is included, so users can select the closure that matches their setup. With a 1000 ml capacity, the flask is suited to solution preparation, mixing, gentle heating and temporary holding of liquids in analytical and synthetic laboratories. Offered as a single piece from manufacturer Hecht, it integrates readily into existing ground-joint systems. The combination of borosilicate glass 3.3, flat-bottom geometry and NS 29/32 joint provides a practical, interchangeable component for general laboratory glassware stocks where standing stability and standard joint compatibility are required.
This article is part of Flat-bottom flasks, in Beakers & flasks.

Questions about Flat bottom flasks, borosilicate glass 3.3, with standard ground joint, without
What is this article?
Flat bottom flasks, borosilicate glass 3.3, with standard ground joint, without is the article on this page. Luminix Health distributes Hecht for laboratory use. It sits in Flat-bottom flasks, inside Beakers & flasks, in Labware.
A flat-bottom flask stands on the bench without a cork ring, which a round-bottom flask will not do. It is for heating on a plate and for simple setups. It is a poorer shape than a round bottom for even boiling under vacuum.
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.
