Description
Kjeldahl flask 250 ml NS 24/29 is a ground-joint laboratory flask with a nominal volume of 0,25 l, made from DURAN tubing in borosilicate glass 3.3 and fitted with an NS 24/29 socket. The larger standard taper joint supports direct coupling to condensers, splash heads and distillation components typically used in Kjeldahl nitrogen analysis and comparable acid-digestion procedures. Net weight is 0,14 kg per flask, and the product is supplied in packs of 10 pc(s) for efficient laboratory replenishment. The classic Kjeldahl profile provides working volume and neck geometry suited to heating, mixing and transfer of digests in protein, feed and environmental sample preparation. Offered by Witeg, the vessel uses DURAN tubing and borosilicate glass 3.3, materials selected for chemical and thermal demands of wet-chemical digestion. Specification of the NS 24/29 socket ensures compatibility with common European ground-joint systems and helps standardise apparatus trains across benches. At 0,25 l capacity, this Kjeldahl flask serves teaching laboratories, quality-control units and research groups that require interchangeable-joint borosilicate glassware for consistent Kjeldahl and related digestion workflows.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flasks Kjeldahl, 250 ml, made from DURA
What is this article?
Flasks Kjeldahl, 250 ml, made from DURA 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.
