This thin-film sensor has a single working electrode with 1 mm diameter.
The Micrux Thin-Film electrodes are reusable and need only 1 to 5 µL measuring solution to be operated. The single electrode sensors are available in platinum or gold electrode. The WE material is sputtered on a 50 nm thick layer of titanium and has a thickness of 150 nm, which is sufficient to show bulk behavior.
Please note that one of the Micrux cells is necessary to connect the electrode.
