What it is

The Struers TenuPol-5 is an electrolytic thinning unit for specimen preparation before transmission electron microscopy.[2][1][3]

The TenuPol-5 is used in a professional laboratory environment and is intended for automated electrolytic thinning of specimens.[1][3]

How it works

The TenuPol-5 works by electrolytically thinning conductive specimens until a surface is prepared for TEM inspection.[1][3]

The TenuPol-5 uses a polishing unit together with a control unit, electrolyte handling, a pump, and cooling water to carry out the thinning process.[1][3]

Where it fits in the process flow

The TenuPol-5 sits in the TEM sample preparation flow before transmission electron microscopy examination.[2][1][3]

The TenuPol-5 is intended for conductive materials and for quality control applications where a specimen surface is prepared for later materialographic inspection with TEM.[1][3]

Applications

The TenuPol-5 is used for preparation of conductive materials suitable for electrolytic etching.[1][3]

The TenuPol-5 is used in materialographic laboratories for specimen preparation work that supports transmitted electron microscope inspection.[1][3]
