Pressure Digestion

DAB-2/3/3XXL

Pressure vessels

The pressure vessels DAB-2, DAB-3 and DAB-3 XXL are equipped with a rupture disc as standard. The medium-affected components of the vessels are made of PTFE. For the DAB-2, DAB-3 and DAB-3 XXL vessles, Berghof offers equivalent heating blocks. Furthermore, the pressure vessles can be heated within an oven.

Range of Applications

Food & feed

  • Digestion of inhomogeneous samples (big amounts)

Environment & geology

  • Digestion of soil

Technology

  • Digestion of difficult to digest samples; solvothermal synthesis; material testing like aging tests

Product Description

The pressure vessels DAB-2, DAB-3 and DAB-3 XXL 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 DAB-2, DAB-3 and DAB-3 XXL pressure vessels convince by an easy handling and can be operated using 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.
