Product Description

Kjeldahl flasks are specialized laboratory vessels designed for the nitrogen determination and digestion process in chemical, environmental, and food analysis. Featuring a round bottom for even heat distribution and a long, narrow neck to minimize loss of sample during boiling, these clear glass flasks are indispensable for protein analysis in accordance with established Kjeldahl methods.

Manufactured from high-quality, chemical-resistant borosilicate glass, these flasks deliver excellent resistance to acids and thermal shock. They are suitable for both manual and automated Kjeldahl systems, offering flexibility across a wide range of analytical volumes.
