LectroPol-7 Electrolytic Polishing and Etching System

LectroPol-7 is an automated electrolytic polishing and etching system for metallographic specimens. A voltage-scanning function supports parameter selection for new materials, while controlled electrolyte flow, temperature monitoring and reusable methods help maintain repeatable preparation conditions.

System type	Automatic electrolytic polishing and etching
Parameter setup	Current-density scan across a defined voltage range
Method database	More than 10 supplied methods; up to 200 custom methods
Control layout	Separate control and polishing units
Interconnection	2 m cable
Electrolyte control	Flow circulation and temperature monitoring
External etching	Preset-time external etching supported
Specimen accommodation	Multiple mask sizes; optional arm for specimens up to 100 mm

Preparation workflow

For a new material, the scanning function measures a current-density curve across a defined voltage range. The curve is used to select a polishing or etching voltage, reducing trial-and-error setup.

Stored methods allow defined settings to be reused for recurring materials and preparation tasks.

Electrolyte and temperature control

The pump can circulate electrolyte before current is applied so that flow is established at process start. Temperature is monitored continuously; cooling can start at a preset limit using mains water or an external cooling unit.

Laboratory configuration

The polishing unit may be installed in a fume cabinet while the separate control unit remains outside for programming and monitoring.
A removable electrolyte container has a lid for closed storage when it is not installed.
External etching is available when polishing and etching require different electrolytes.
Different mask sizes define the preparation area; an optional extension arm accommodates specimens up to 100 mm high.

Process safeguards

The system monitors electrolyte temperature, voltage and current. Depending on the limit reached, it can warn the operator, stop the process or reduce settings. A transparent cover forms a barrier around the polishing area while keeping it visible.
