Description
Round-bottom flask 2000 ml with two necks, centre neck NS 29/32 and straight side neck NS 14/23, is a clear-glass laboratory vessel made from borosilicate glass 3.3. The nominal volume of 2 l and stable round-bottom geometry support even heat distribution during distillation, reaction work and collection of distillates. Two ground-joint necks allow simultaneous attachment of condensers, dropping funnels or other standard glassware while the main joint NS 29/32 and side joint NS 14/23 remain fully compatible with common laboratory apparatus. Manufactured from chemically resistant borosilicate glass 3.3, the flask withstands typical thermal cycling encountered with heating mantles or oil baths. Net weight is 0,498 kg. This two-neck design from manufacturer Witeg is well suited to organic synthesis, solvent recovery and multi-step preparative procedures that require an additional port. Supplied as a single piece, the flask belongs to the family of ground-joint round-bottom, distillation and receiving flasks used throughout research, quality-control and teaching laboratories where reliable multi-neck vessels are essential.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Round bottom flask 2000 ml two necks CN ST 29/32 +
What is this article?
Round bottom flask 2000 ml two necks CN ST 29/32 + 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.
