LectroPol-7

Automatic electrolytic polishing and etching with short preparation times and reproducible results.

LectroPol-7 facts

  • Scanning function for easy parameter determination
  • Built-in safety features
  • Special etching methods using low-concentration electrolytes
  • Method database with Struers standard methods and up to 200 custom methods
  • Suitable for external etching
  • Appropriate for multiple specimen sizes
  • Cover for increased safety

LectroPol-7 automates electrolytic polishing and etching of metallographic specimens. Its scanning function helps you select a suitable voltage for a new material, while controlling electrolyte flow, temperature monitoring, and stored methods support repeatable preparation.
The system consists of a control unit and a polishing unit connected by a 2 m cable. The polishing unit can be placed in a fume cabinet, while the control unit is used to program and monitor the process.

Find suitable settings with less trial and error

When you work with a new specimen material, the scanning function measures a current-density curve across a defined voltage range. Use the curve to select a suitable voltage for polishing or etching instead of relying solely on repeated parameter trials.

Repeat a preparation method with confidence

Stored methods help you apply defined settings when preparing recurring materials. Controlled electrolyte flow and temperature monitoring support consistent process conditions, while the pump can circulate electrolyte before applying current, supporting even flow from the start.

Set up the process to suit your laboratory

The separate control and polishing units give you flexibility in where you place the equipment. Position the polishing unit in a fume cabinet while programming and monitoring the process from the control unit outside the fume cabinet. External etching is also available when polishing and etching require different electrolytes.

Enhanced operator safety

LectroPol includes safety functions designed to protect the operator.
LectroPol-7 monitors electrolyte temperature, voltage, and current during preparation. Depending on the limit reached, the system can issue a warning, stop the process, or reduce the settings. A transparent cover helps protect the operator while keeping the preparation area visible.
