Detailed Parameters Of The Product
    EQ-Unipol-300 is an automatic mini-grinder / polisher for preparing TEM, metallographic samples in a single mount. The machine equips with many advanced features, such as 3" fix lapping plate, variable sample moving speed, adjustable pressure load and selectable time switch to achieve attention free polishing. Unipol 300 simulates human hand to grind and polish sample via randomly moving sample holder on top versus fixed 3" plate.
