Description
Round-bottom flask 50 ml two necks centre neck + side neck NS 14/23 angled is a laboratory flask equipped with two necks comprising a centre neck NS 14/23 and a side neck angled at 20° with matching NS 14/23 joint. Manufactured as clear glass from borosilicate glass 3.3, the flask has a nominal volume of 50 ml. This item from manufacturer Witeg is intended for use as a round-bottom flask, ground-joint flask, distillation flask or receiving flask in laboratory practice. The two-neck layout allows parallel connection of additional apparatus such as reflux condensers, addition funnels or temperature probes while maintaining a closed system. Delivered as 1 pc(s) with a net weight of 0,054 kg, the flask is convenient for medium-small scale reactions and distillations. Clear glass enables direct observation of the process contents throughout heating or cooling steps. Standard NS 14/23 joints guarantee compatibility with widely used laboratory glassware. The angled side neck at 20° improves spatial arrangement of attached components around the centre neck. With 50 ml capacity the flask supports organic synthesis, solvent recovery and sample collection tasks commonly performed in research, teaching and quality-control laboratories.

Questions about Round bottom flask 50 ml two necks CN + SN
What is this article?
Round bottom flask 50 ml two necks CN + SN is the article on this page. Luminix Health distributes Witeg 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.
