Description
Round flasks in DURAN® transparent glass with a 10000 ml working volume and an NS 45/40 ground joint provide a large-capacity vessel for demanding laboratory workflows. The clear glass body supports visual monitoring of contents during heating, mixing, or solvent handling, while the standardised conical joint ensures reliable connection to condensers, adapters, and other ground-glass components. Supplied as a single piece and weighing 2,008 kg, this flask is suited to distillation setups, Soxhlet-type extractions, and sample preparation steps where substantial liquid volumes must be processed under controlled conditions. Manufactured by Lenz, the DURAN® construction offers the mechanical and thermal robustness expected of laboratory round flasks used in environmental analysis and routine preparative work. The generous capacity makes the vessel practical for bulk solvent recovery, large-scale reflux, and intermediate storage of process liquids before further treatment. Transparent walls aid inspection of phase separation, boiling behaviour, and residue formation without interrupting the experiment. Designed for integration into classical glassware trains, the NS 45/40 joint matches common large-scale apparatus, supporting secure, leak-resistant assemblies in research and analytical laboratories that require durable, high-volume round flasks.
This article is part of Round-bottom flasks, in Beakers & flasks.

Questions about Round flasks,DURAN®, transparent glass, 10000 ml, NS 45/40, 1 unit(s)
What is this article?
Round flasks,DURAN®, transparent glass, 10000 ml, NS 45/40, 1 unit(s) is the article on this page. Luminix Health distributes Lenz 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.
