The reactor is a vessel with a volume of 1.5 liters with a lid with flange fastening to the vessel body. The autoclave provides stirring of the medium using a magnetic insulated element. The magnetic field has a rotation frequency of up to 1000 rpm. Due to the non-contact stirring method, the reliability and the tightness of the autoclave are increased. To research the corrosion processes in the autoclave sample holders are applied.
