Description
Flat-bottom flask with NS 45/40 is a laboratory vessel for chemical work that needs a stable standing flask with a large standardised ground joint and greater working volume. This 250 ml flask features ground joint NS 45/40 for connection to compatible condensers, adapters, stoppers and other NS 45/40 glassware. Supplied in a pack of 10 pieces, it is practical for teaching laboratories, parallel preparations and routine workflows that consume several identical vessels. The flat base allows the flask to stand on the bench during charging, weighing or short-term holding of mixtures when loads remain moderate. These flat-bottom flasks from manufacturer Dinkelberg suit general laboratory use in research, quality control and education. Origin is the Czech Republic. The large NS joint supports interchangeability within common European glassware systems and helps keep multi-piece assemblies consistent. Typical applications include dissolving solids, mixing at intermediate volumes, temporary storage of solutions and heating on a hot plate with appropriate support and safe laboratory practice. Select this 250 ml NS 45/40 pack when you need multiple matching flat-bottom flasks for efficient laboratory operations.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask, flat bottom with SJ 45/40, 250ml, 10/PK
What is this article?
Flask, flat bottom with SJ 45/40, 250ml, 10/PK is the article on this page. Luminix Health distributes Dinkelberg 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.
