Description
Rotilabo®-double neck round bottom flask is a 250 ml borosilicate glass reaction and distillation vessel with ground glass joints NS 29/32 (14/23). The round-bottom body supports uniform heating and mixing, while the double-neck layout allows simultaneous connection of condensers, dropping funnels, thermometers or inert-gas lines in multi-port setups. Borosilicate glass provides the chemical and thermal resistance needed for standard organic synthesis, reflux and sample preparation work. Joint sizes NS 29/32 and NS 14/23 match common European laboratory glassware systems, enabling straightforward assembly with existing ground-joint components. Supplied as one piece and weighing 0,135 kg, this flask belongs to the Rotilabo® range from manufacturer ROTH SELECTION. It is suited to research, development and teaching laboratories that require compact multi-neck round flasks for small-scale reactions, distillations and controlled atmosphere experiments. Clear glass construction permits visual observation of contents throughout heating and stirring operations in routine labware applications.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Rotilabo®-double neck round bottom flask, 250ml, borosilic.glass, NS29/32(14/23)
What is this article?
Rotilabo®-double neck round bottom flask, 250ml, borosilic.glass, NS29/32(14/23) 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.
