The Stirrer-Bar\white PVDF\15×6 mm operates in the 2-mL O2k-Chamber at constant stirring speed (standard is 750 rpm, or 12.5 Hz) to provide optimum mixing of the sample in the aqueous medium. This ensures a stable signal of the POS, which is placed at position where there is maximum current.
Two units of this item are standard components of the O2k-Assembly Kit (O2k-Packages).
