Description
Flat-bottom flask 50 ml, narrow neck is compact laboratory glassware made from borosilicate glass 3.3 for small-scale reactions, sample storage and general bench work. The stable flat base allows the vessel to stand independently on hotplates or laboratory benches without additional support, while the narrow neck with beaded rim accepts stoppers or simple adapters securely. Nominal volume of 0,05 l suits micro-scale synthesis, titrations and temporary holding of solutions. Borosilicate glass 3.3 provides strong resistance to chemicals and thermal shock, supporting safe heating and cooling cycles. Packed ten pieces per carton from manufacturer Marienfeld, these flasks are convenient for everyday laboratory use. The clear wall enables easy visual inspection of contents, and the robust construction endures repeated washing. Ideal for teaching laboratories, analytical workflows and preparative steps where a free-standing flask of modest capacity is required.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Boiling flasks with flat bottom 50 ml, narrow neck
What is this article?
Boiling flasks with flat bottom 50 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.
