Description
Rotilabo® double-neck round-bottom flask is a borosilicate glass laboratory vessel with a capacity of 4000 ml and ground joints NS 45/40 and NS 14/23. The dual-neck configuration supports parallel attachment of condensers, dropping funnels, probes or inert-gas lines during larger-scale reactions, distillations and preparative chemistry. A rounded base promotes uniform heat transfer under heating mantles or baths and aids mixing of reaction mixtures. This Rotilabo® flask from manufacturer ROTH SELECTION is offered as 1 pc with a weight of 0,800 kg. Borosilicate glass delivers the mechanical and thermal performance expected for solvent work, synthesis and process development. Compatible joint geometry allows use with standard laboratory adapters and stoppers for closed or semi-closed setups. Ideal for chemical, pharmaceutical and analytical labs that need multi-port round-bottom glassware for flexible handling of substantial liquid volumes among round flasks and flasks with ground glass joints.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Rotilabo®-double neck round bottom flask, 4000ml, borosilic.glass
What is this article?
Rotilabo®-double neck round bottom flask, 4000ml, borosilic.glass is the article on this page. Luminix Health distributes Carl Roth 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.
