Description
Kjeldahl flask 100 ml NS 24/29 is a laboratory glass vessel designed for classical Kjeldahl digestion and related wet-chemical nitrogen determinations. With a nominal volume of 0,1 l and a standard ground joint NS 24/29, it connects securely to condensers, adapters and other jointed glassware used in digestion trains. The pear-shaped body supports controlled boiling and efficient mixing of sample and acid mixtures during prolonged heating. Supplied in packs of 10 pc(s), the flask has a net weight of 0,074 kg and is intended for routine analytical workstations. This model from manufacturer Witeg is specified with a ground joint sleeve NS 24/29, matching common European laboratory joint systems. Typical applications include protein and total nitrogen analysis in food, feed, environmental and agricultural laboratories, as well as general acid digestions that benefit from a stable, jointed Kjeldahl flask geometry. The clear glass construction allows visual monitoring of the reaction mixture throughout the digestion cycle, supporting reproducible sample preparation workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kjeldahl-flask, 100 ml, with socket ST 2
What is this article?
Kjeldahl-flask, 100 ml, with socket ST 2 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.
