Description
Kjeldahl flask, 250 ml is a laboratory digestion flask intended for Kjeldahl nitrogen determination and other wet-chemical boiling or acid-digestion procedures that benefit from a long neck and rounded body. The geometry assists vapour management, reduces splash-out risk and gives a stable profile when heated in suitable blocks or mantles during extended digestions. This version provides a 250 ml capacity and comes as a pack of 10 pieces from manufacturer Dinkelberg, making it practical for batch analyses in food, feed, environmental, agricultural or academic laboratories that still rely on classical Kjeldahl-style workflows. The goods originate from the Czech Republic and belong to the laboratory materials range used for everyday analytical glassware needs. The 250 ml volume suits mid-size sample portions and method protocols that exceed micro-scale flasks yet remain manageable on a standard digestion rack. Selecting this 250 ml Kjeldahl flask multipack supports consistent parallel processing, straightforward stock replenishment and clear identification of vessel size in SOPs, without further fittings or performance grades being stated for this specific item.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Flask Kjeldahl, 250ml, 10/PK
What is this article?
Flask Kjeldahl, 250ml, 10/PK is the article on this page. Luminix Health distributes Dinkelberg 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.
