Description
Flat-bottom flask with NS 45/40 ground joint and a nominal capacity of 2000 ml is laboratory glassware intended for general chemistry, preparative tasks, and stable bench-top work. Its flat base provides a secure standing position without additional support rings, making the vessel convenient for mixing, temporary solution storage, and assemblies that need a broad, steady footprint. The larger standardised NS 45/40 joint allows reliable connection to matching condensers, funnels, stoppers, and adapters commonly found in teaching and research laboratories. Supplied in a pack of 6 pieces, this presentation is practical for laboratories that require several identical flasks for parallel runs, shared workstations, or recurring protocols. These flat-bottom flasks from manufacturer Dinkelberg are of Czech origin and form part of everyday laboratory material ranges used in analytical, synthetic, and educational settings. Combining a 2000 ml volume with the NS 45/40 joint supports solvent handling, intermediate holding, and multi-step procedures where joint compatibility and vessel interchangeability are important. Explicit joint and volume identification helps ensure correct pairing with existing ground-joint equipment.
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, 2000ml, 6/PK
What is this article?
Flask, flat bottom with SJ 45/40, 2000ml, 6/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.
