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.
Accessories
Set of mounting tools for save closing and opening of DAB vessels.
Temperature regulation between 50° C and 320° C as well as maximum user safety through insulation and cladding.
Monitoring and controlling of heating for all Berghof reactors.
Effective heating processes for both Berghof reactors and pressure vessels.
Suitable for all Berghof reactors.
Suitable for all Berghof reactors.
Application Notes
Oil can be digested using the Berghof DAB-3 pressure vessel.
Rocks can be digested in an acid solution using the Berghof DAB pressure vessels.
For the digestion of graphite, the Berghof pressure vessel system DAB can be used.
Test samples of elastomers are prepared in coolants for tensile tests using Berghof reactors.
Using Berghof reactor technology, elastomers can be prepared in blow-by-mixtures for tensile tests.
Berghof reactors for hydrothermal syntheses or for both sol-gel synthesis and hydrothermal synthesis.
