Pressure Vessel


Metal-free reactor

The metal-free reactors DB-300 to DB-700 consist of a complete PTFE lining. As standard, all DB reactors are equipped with a rupture disc and a valve. In addition, extensions for temperature and pressure monitoring are available. Those components of the extensions, that go inside the reactor, are made of PTFE, as well.

Range of Applications


  • Customized applications like experminets with highly corrosive reagents

Product Description

All PTFE components of the DB-300, DB-500 and DB-700 metal-free reactors are made by the Berghof Fluoroplastics Technology GmbH. One of the characteristics of PTFE is an over-average corrosion resistance. Therefore, the DB-300, DB-500 and DB-700 reactors can be used for experiments with highly corrosive reagents.

In addition to the metal-free reactors, Berghof offers also relevant accessories. These are e.g. different heating systems and controller units. The DB-300 reactor offers a special feature: When using a hot plate for heating, stirring via a magnetic stir is possible, too.
