Description
Kjeldahl flask 500 ml Boro is a borosilicate glass digestion flask for classical Kjeldahl nitrogen analysis and comparable wet-digestion workflows. Made from borosilicate glass 3.3, it is specified with a nominal volume of 0,5 l, flask diameter 101 mm, height 300 mm, and neck diameter 34 mm. These dimensions support stable seating in heaters and secure clamping during prolonged boiling of acid digests.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.
Borosilicate glass 3.3 withstands the temperature changes and corrosive reagents typical of Kjeldahl sample preparation. The long-neck form helps contain foam and aerosols when organic matrices are mineralised. Net weight is 0,282 kg per flask. Supplied in packs of 10 pieces from manufacturer Witeg, the flasks serve laboratories that need a straightforward 500 ml borosilicate option for total nitrogen or protein determination. Defined outer diameters and height make it easier to match existing racks, mantles, and distillation setups without re-engineering the glassware train for each batch of samples.

Questions about Flasks, Kjeldahl, borosilicate-glass, 50
What is this article?
Flasks, Kjeldahl, borosilicate-glass, 50 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.
