Kjeldahl Digester

MBC Series

Our Kjeldahl digesters represent a compact block digestion system, standing out for its efficiency, versatility, and scalability to perform safe Kjeldahl digestions. This internationally recognized reference method is used to analyze nitrogen and protein content in various fields of application. Moreover, these digesters are utilized for sample pretreatment (hydrolysis) for subsequent fat extraction and soil digestion for metal analysis.

The new generation of MBC Series digesters has enhanced its process control thanks to a 5-inch color touch screen and Wi-Fi connection for result analysis in RAYPAnet. The new microprocessor allows for advanced programming of cycles and the timer, offering up to 10 customizable program names according to the application note, and configurable with up to 10 temperature segments.

To adapt to the specific needs of each laboratory, we offer a wide range of models of our Kjeldahl digesters. These range from the most compact models with 6 positions to those designed for centers with a high volume of tests, capable of handling up to 40 positions simultaneously.

KJELDAHL DIGESTION WITH OUR COMPACT BLOCK DIGESTION SYSTEM CONNECTED WITH OUR SCRUBBER

After loading the samples with the corresponding reagents within the samples tubes rack, the sample tubes rack is placed inside the heating block and the fumes collector is placed on top of the sample tubes rack. The next step is choosing the appropiate program and the equipment starts to heat up, following the predefined time and temperature segments.
In the process, exhaust fumes are generated that are completely captured by the fumes collector which in turn are mechanically displaced into the SCRUBBER through the vacuum pump that the SCRUBBER posseses.
The exhaust fumes that enter the SCRUBBER undergo a phase of condensation that acts as preliminary extractor for steams and dragged liquids, avoiding warming or volume increasement in the posterior wash-up solution. The acid or alkaline vapors are then washed and neutralized in the next step. In the final step, most of the remaining particles are retained through granules of activated charcoal.
