Platinum Spooled Wire

Platinum spooled wire is used in thermocouple sensors, fuel cell electrodes, and electrochemical research due to its stable electrical conductivity, high melting point (1,768 °C), and corrosion resistance in reactive environments. In analytical chemistry laboratories, it is ideal for precise measurements in high-temperature reactions and trace element detection. Its ductility and purity make it suitable for custom configurations in spectroscopy, catalysis, and vacuum systems. Platinum spooled wire is widely applied in hydrogenation reactions, environmental monitoring (e.g., catalytic gas sensors), and chemical process control, as well as in catalytic converters for automotive systems. It also plays an essential role in microelectronics research for bonding to semiconductors and in high-vacuum instrumentation.
