Electrolytic Polishing and Etching Machine

ELOPRPEP is a fully automatic electrolytic polishing and etching equipment with independent control unit. Shorter preparing time is needed for electrolytic polishing and etching process compared to traditional mechanical preparation.

Electrolytic Polishing

The eloprep has advanced techniques and software with programmable coloured HMI touch screen controls, increasing the productivity, sample consistency and operator comfort. All speed, etc. can be monitored during the process. The speed of the amount to be pumped is also variable.

Exchangeable Electrolyte Cartridge


Eloprep has two separate units, the control unit and the polishing unit. Separate polishing and etching unit can be placed away from the control unit and can be installed under a fume extraction system. The electrolyte cartridge is easily exchangeable and inserted into the polishing and etching unit.

With the scanning function of Eloprep, correct voltage of polishing as well as etching can be defined automatically.

The sample is placed on the polishing and etching table where optional masks are available as 0.5 cm2 - 5cm 2. The cooling tube is fixed to the lid and directly lowered into the container. Eloprep has the highest safety standards. The cooling water is automatically switched on as the set temperature is reached. The cooling water is activated with a solenoid valve.
