Description
Round flasks DURAN® transparent glass are large-volume laboratory flasks offering a 6000 ml capacity and a standard ground joint NS 45/40 for connection to matching condensers, adapters and jointed accessories. Fabricated from transparent DURAN® glass, the vessel permits continuous visual observation of reaction mixtures, solvents or distillates throughout heating, stirring and transfer operations. The round-bottom form promotes uniform heat uptake when paired with appropriate mantles or baths in preparative laboratory work. Delivered as 1 pc, this flask supports distillation, sample preparation and related applications that demand both substantial volume and a larger NS 45/40 joint. This round flask from manufacturer Lenz combines transparent DURAN® glass with the NS 45/40 interface for secure, interchangeable apparatus assembly. Weighing 1,361 kg, the flask is designed for stable mounting in standard laboratory frameworks. The 6000 ml working volume suits environmental analysis workflows, sampling tasks and distillation arrangements where clear glassware and a defined ground joint are required. Laboratories building or expanding jointed glass setups will value the specified capacity, transparent construction and NS 45/40 joint dimensions for reliable day-to-day use.
This article is part of Round-bottom flasks, in Beakers & flasks.

Questions about Round flasks,DURAN®, transparent glass, 6000 ml, NS 45/40, 1 unit(s)
What is this article?
Round flasks,DURAN®, transparent glass, 6000 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.
