State-of-the-art digestion units provide accurate and reproducible results with an excellent recovery rate for applications in food and beverage, feed, chemical and pharmaceutical industry labs
Buchi offers complete Kjeldahl systems including sample preparation (eg homogenising), digestion, distillation of steam volatile components and the analytical determination (eg titration).
A variety of instruments for digestion and distillation is designed to meet specific requirements.
Buchi offers manual to fully automatic distillation systems and different types of digestion units.
The latest innovations of the wide range of Kjeldahl solutions are the distillation units K-350, K-355 and K-370.
These state-of-the-art units provide accurate and highly reproducible results with an excellent recovery rate.
They can be used for a variety of applications in analytical or quality labs of the food and beverage, feed, chemical and pharmaceutical industry as well as labs of the agricultural and environmental area.
These applications also include the classical nitrogen and protein determination (Kjeldahl, Devarda, TKN) in accordance with official methods, such as AOAC, EPA, ISO and Din.
The K-350 is the easy-to-use Kjeldahl distillation unit for the classical nitrogen and protein determination in accordance with official methods.
In addition to the classical applications, the K-355 can be used for an extended range of official distillation methods.
This includes applications requiring reduced steam output or the dosage of strong acids.
Therefore, the K-355 features an acid-resistant pump enabling automatic addition.
Examples of additional applications on the K-355 are alcohol or phenol distillation and the determination of sulphur dioxide or volatile acids.
The K-370 is a fully automated distillation unit, meeting the most demanding requirements.
The multitasking software even allows the operator to simultaneously carry out measurements and prepare new measuring- and process output data.
Buchi has been a pioneer in the development of instruments related to distillation applications (including Kjeldahl), from the use of the first steam generator in a Kjeldahl apparatus to the revolutionary new steam sample transfer mechanism.
Buchi traces its roots back more than 65 years, from a humble beginning as a glass blowing shop in a basement to an innovative world leader with a global network of scientific excellence.
