Pressure digestion vessels  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 , 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.

These pressure vessels have a wide range of applications. They can be used ideally for digestions of big sample amounts or inhomogeneous samples, like soil or milk powder. Furthermore, they are often used for solvothermal synthesis or for material tests like aging tests.

The pressure vessels are easy to handle and can be operated using just one hand only. In addition, an opening station is available. By the use of this station, opening the pressure vessels becomes even more easy. Different heating systems allow the heating of various pressure vessels at the same time.
