Description
Kjeldahl flask, DURAN®, with standard ground joint 19/26 is a 50 ml laboratory flask designed for analytical work that depends on a precise ground-glass connection. Fabricated from DURAN® glass, it follows the established Kjeldahl profile used in digestion and complementary wet-chemistry operations. The standard ground joint 19/26 enables dependable attachment to condensers, adapters and matching jointed glassware. Supplied as 1 pc with a weight of 0,065 kg, the flask is available from manufacturer Lenz among round flasks and flasks with ground glass joints. The compact 50 ml volume is practical for smaller sample loads and space-conscious bench setups that still require an NS 19/26 interface. Transparent DURAN® construction allows continuous visual monitoring during heating and reaction sequences. Laboratories that specify a 50 ml Kjeldahl flask with standard ground joint 19/26 can incorporate this unit into existing glass assemblies for research, routine analysis and instructional environments without altering established joint conventions.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kjeldahl flask, DURAN®, with standard ground joint 19/26, 50 ml, 1 unit(s)
What is this article?
Kjeldahl flask, DURAN®, with standard ground joint 19/26, 50 ml, 1 unit(s) is the article on this page. Luminix Health distributes Lenz 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.
