Kjeldahl Method
Below is a schematic of the Kjeldahl method and the intricacies and steps involved. The second schematic shows the power of automation with Gerhardt.
If the Kjeldahl method for crude protein (AOAC 990.03) is being used, we offer a comprehensive solution to streamline this time-consuming process, making it efficient, safer, faster, reproducible, and more precise.
Our KJELDATHERM block digestor, paired with the VACUSOG fume scrubber, is designed for flexibility. Its automatic and programmable heating saves valuable time, while the preheated digestion block awaits your samples. With a range of tube sizes accommodating 8, 20, or 40 samples at a time, even foamy, fatty, and heterogeneous samples are handled with ease.
Following digestion, simply move your samples to the VAPODEST steam distillation system, which delivers results in just 4 minutes. Our VAPODEST series offers various models with different degrees of automation, catering to your specific needs. From the straightforward smart version suitable for a small number of samples to fully automated systems featuring integrated titration and an autosampler for high sample throughput, we have you covered.
