99.99% Pure Pt Wire, Platinum Wire Electrode, electrophoresis Cell Electrode

1. overview of materials
The atomic number of platinum is 78, which is a noble metal. Platinum's pure metal is silver white. The chemical properties of platinum are very stable, insoluble in strong acid and strong alkali, and do not oxidize in air. Platinum has good ductility and can be drawn into very thin platinum wire and rolled into very thin platinum foil.
