RRDE-3A Rotating Ring Disk Electrode Instrument

Rotating Ring Disk Electrode Instrument RRDE-3AA high-precision electrode rotator for electrochemical measurement of a rotating ring disk based on fluid dynamics control. The rotational speed of RRDE-3A is controlled by PWM (pulse width modulation) signals. The electrodes are small and can be quickly exchanged. The instrument is equipped with an adjustable valve system inside, which can use inert gas to blow and clean the electrolytic cell.

Rotating disk electrode instrument (ring disk)Choose disc electrode or ring electrode as the working electrode according to the purpose, these electrodes can be easily installed and disassembled, and maintenance is simple. There are multiple options for reference electrodes and counter electrodes. RRDE-3A can be manually controlled independently or connected to an electrochemical analyzer for remote control through a computer.
