Description
Kjeldahl flask 250 ml with NS 29/32 standard ground joint is produced from heat-resistant, durable borosilicate glass conforming to DIN 12360. Its elongated neck supports efficient Kjeldahl digestion and nitrogen determination as well as other wet-chemical digestion methods. Thick walls, a heavy base and a reinforced rim help prevent breakage during cleaning, handling and thermal cycling. The precisely ground NS joint with smooth interior delivers a reliable, leak-proof connection to compatible condensers, adapters or stoppers. White enamel graduations and labelling stay clearly visible in everyday laboratory use. Available as one piece from manufacturer ISOLAB Laborgeräte, this 250 ml flask suits routine protein and nitrogen analysis, sample preparation and educational settings. Borosilicate construction provides the thermal and chemical resistance needed for concentrated acid work, while the NS 29/32 joint integrates easily into standard glassware trains. A robust mid-volume option for laboratories performing classical Kjeldahl procedures.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about flask - kjehldahl - 29/32 - 250 ml
What is this article?
flask - kjehldahl - 29/32 - 250 ml is the article on this page. Luminix Health distributes ISOLAB 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.
