Description
Flat-bottom flask 1,000 ml, narrow neck is a laboratory standing flask manufactured from borosilicate glass 3.3. It combines a stable flat base with a narrow neck and beaded rim, supporting secure placement on the bench and controlled handling during filling, mixing or transfer steps. The nominal volume of 1 l makes the vessel suitable for solution preparation, reagent holding, heating and general wet-chemistry work in research, teaching and quality-control laboratories. Borosilicate glass 3.3 provides the thermal-shock resistance and chemical durability required for routine laboratory cycles. The beaded rim improves grip and mechanical robustness at the opening, while the narrow-neck geometry accommodates stoppers and reduces evaporation or spillage risk. Packed as 10 pieces in cartons from manufacturer Marienfeld, these flasks offer a practical multi-unit supply for laboratories that need consistent glassware for daily analytical and preparative tasks. Clear walls allow easy visual inspection of contents, and the overall design supports efficient workflow on hot plates or standard work surfaces without additional stands.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flasks with flat bottom 1'000 ml, narrow neck
What is this article?
Boiling flasks with flat bottom 1'000 ml, narrow neck is the article on this page. Luminix Health distributes Marienfeld 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.
