DPF-2 Polishing and Electro Etching Machine with Bunsen Beaker

DPF-2: Ditch Vibratory Polishers for True Metallographic Accuracy‌‌

Tired of vibratory polishers leaving embedded abrasives or distortion in soft metals? The ‌DPF-2 Electrolytic Polishing and Etching Machine‌ skips mechanical grinding entirely. Designed for ‌non-ferrous metals‌ (titanium, aluminum, copper) and ‌high-temperature alloys‌, this lab-grade system uses ‌adjustable DC current (0-60V)‌ to dissolve surface layers atomically. No deformation. No artifacts. Just pristine samples for SEM, EDS, or weld analysis. Load your specimen, set voltage/time, and let electrochemistry do the work.

‌Key Benefits :‌

• ‌Zero Mechanical Damage‌: Electrolytic polishing ‌erases deformation layers‌ from vibratory/mechanical methods.
• ‌Precision Control‌: Adjust voltage (0-60V) and current (0-25A) for soft aluminum or hardened Inconel.
• ‌Large Sample Ready‌: Polish/etch welds or oversized specimens (up to 300x230mm workspace).
• ‌Dual Function‌: Polish ‌and‌ etch in one cycle – perfect for microstructure revelation.
• ‌Lab-Safe Design‌: Compact, spill-resistant electrolyte tanks (300-1000ml capacity).

DPF-2 electrolytic polishing and etching machine is a metallographic sample preparation machine which combines electrolytic polishing and etching function, suitable for use in factories, universities, research institutions and other laboratories. The machine uses the electrochemical principle to do metallographic sample preparation. The samples which adopt electrolytic polishing and etching avoid the deformation layer caused by the mechanical polishing, so the organization is true without illusion. Therefore it is the best method of preparation of titanium, aluminum, copper and other non-ferrous metals and high-temperature alloy samples. The instrument is designed to have higher operating voltage and operating current, metallographic preparation for the larger size of the sample, especially suitable for welding metallographic sample preparation.
