Description
2-Neck pear-shaped flask 50 ml with angled side neck is a laboratory glassware item manufactured to DIN 12383. It features a center neck (MH) with ground joint NS 19/26 and an angled side neck (SH) with ground joint NS 14/23. The nominal volume is 50 ml (0,05 l). The pear-shaped design concentrates liquid in the lower portion of the vessel, which is advantageous for small- to medium-scale heating, reaction and distillation procedures. This flask from manufacturer Witeg is supplied as 1 pc and has a net weight of 0,042 kg. The two-neck configuration with the side neck set at an angle allows concurrent connection of condensers, addition funnels, thermometers or other NS-compatible apparatus without mutual interference. Compliance with DIN 12383 guarantees interchangeability of the ground joints with corresponding laboratory glassware. The 50 ml capacity is well suited to organic synthesis, preparative work and general chemical laboratory applications that require a compact two-neck pear-shaped flask of intermediate volume.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about 2-Neck Pear-Shaped Flask 50 ml, MH NS 19/26, Angled Side Neck
What is this article?
2-Neck Pear-Shaped Flask 50 ml, MH NS 19/26, Angled Side Neck 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.
