Pressure digestion vessels from Berghof are the systems of choice when it comes to difficult samples, large sample masses, or in labs that value high levels of flexibility. Typical digestion times lie in the range of 2-4 hours. For difficult to digest samples (e.g., SiC), the ability to extend digestion time for practically any desired period represents a decisive advantage. Microwave units cannot be employed for such applications. An additional advantage over microwave systems lies in the fact that larger sample quantities (e.g., 2 g organic samples) can be digested because of the larger available pressure range up to 200 bar / 2900 psi.
