Description
Kjeldahl flask with standard ground joint, 250 ml, LBG 3.3 is a laboratory glassware item designed for nitrogen determination workflows. Manufactured from borosilicate glass LBG 3.3, it combines chemical resistance with thermal stability suited to digestion and distillation steps typical of Kjeldahl analysis. The nominal volume is 0,25 l, and the flask is supplied with a standard ground joint for secure connection to condensers and other ground-joint apparatus. This pack contains 2 pieces and has a net weight of 0,420 kg. The LBG product type designation reflects the borosilicate 3.3 glass construction used across many analytical glassware lines. Offered from manufacturer Labbox, the flask supports routine nitrogen determination in food, feed, environmental, and chemical laboratories where reproducible glassware geometry and joint compatibility matter. Clear volume marking and robust wall construction help maintain reliable handling during heating and cooling cycles. Ideal for method setups that require interchangeable standard ground joints and durable borosilicate performance without unnecessary complexity in everyday Kjeldahl sample preparation and analysis.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Kjeldahl flask, 250 ml, LBG 3.3, 2 pcs
What is this article?
Kjeldahl flask, 250 ml, LBG 3.3, 2 pcs is the article on this page. Luminix Health distributes Labbox 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.
