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.<br>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.</p><h2>How does LectroPol support your Electrolytic Preparation</h2><h3>Find suitable settings with less trial and error</h3>\n<p>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.</p>\n<h3>Repeat a preparation method with confidence</h3>\n<p>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.</p>\n<h3>Set up the process to suit your laboratory</h3>\n<p>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.</p>\n<h3>Enhanced operator safety</h3>\n<p>LectroPol includes safety functions designed to protect the operator.<br>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.</p><img src=\"/files/struers-file-e2c92751ba60728e0e250887/website-8-974x1000-lectropol-7_0277.png\" alt=\"LectroPol-7 with saved and standard electropolishing methods\" loading=\"lazy\"><p>Save personalized electropolishing methods or use predefined standard methods</p><img src=\"/files/struers-file-fc9c50a0ad9711c9206272db/website-6-974x1000-lectropol-7_0110.png\" alt=\"LectroPol-7 separated control unit and polishing unit\" loading=\"lazy\"><p>Separated control and polishing units provide flexible electrolytic polishing setup</p><img src=\"/files/struers-file-50545a652354074a2b8e3798/website-12-974x1000-lectropol-7_0310.png\" alt=\"LectroPol-7 electrolyte container with lid\" loading=\"lazy\"><p>Changeable electrolyte container with lid for safe electrolyte handling</p><img src=\"/files/struers-file-965af614de9e53548309c811/website-10-974x1000-lectropol-7_0268.png\" alt=\"LectroPol-7 external electrolytic etching function\" loading=\"lazy\"><p>Optional external electrolytic etching with preset etching time</p><p>The scanning function measures the current-density curve across a predefined voltage range, helping you select a suitable voltage for polishing or etching a new specimen material.</p><h2>Scanning function</h2><img src=\"/files/struers-file-741d322b78ebf884fb5b43ed/1024x759-software-method-titanium.png\" alt=\"\" loading=\"lazy\"><p>The method database lets you store preparation settings and reuse them for recurring materials and tasks.
