    "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",

  "summary": "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.",

    {
      "heading": "Preparation workflow",
      "paragraphs": [
        "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."
      ]

    {
      "heading": "Electrolyte and temperature control",
      "paragraphs": [
        "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."

      "heading": "Laboratory configuration",
      "items": [
        "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."

      "heading": "Process safeguards",
      "paragraphs": [
        "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."
