Description
Round-bottom flask 100 ml two necks centre neck + side neck NS 14/23 angled is a laboratory flask provided with two necks: a centre neck finished NS 14/23 and a side neck angled at 20° also with NS 14/23 joint. Fabricated as clear glass from borosilicate glass 3.3, it presents a nominal volume of 100 ml. This flask from manufacturer Witeg serves as a round-bottom flask, ground-joint flask, distillation flask or receiving flask for everyday laboratory operations. The dual-neck design permits concurrent attachment of condensers, dropping funnels or measuring devices while the main neck remains free for stirring or sampling. Offered as 1 pc and weighing 0,06 kg net, the flask is well suited to moderate-scale preparations. Clear glass construction allows uninterrupted visual control of the contents during heating, reflux or collection steps. The standardised NS 14/23 joints ensure ready interchange with other laboratory glass components. The 20° angled side neck optimises the geometry of multi-piece assemblies around the centre neck. With its 100 ml capacity the flask is practical for organic reactions, distillations and product isolation procedures carried out in chemical research and analytical laboratories.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 100 ml two necks CN + SN
What is this article?
Round bottom flask 100 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.
