The Dual Microiontophoresis Current Generator is an electrically isolated, battery-operated instrument designed for the electro-iontophoresis of dyes, drugs and charged substances from micropipettes. Two identical battery operated current generators are available. In ordinary use, the two current generators are operated in parallel providing two distinct currents; one for preventing substances in the micropipette from outward diffusion (the retain or hold current) and the second for actively ejecting charged material. For pipettes with submicron tips, a hold current may not be necessary if there is little outward diffusion of pipette material. Model 260 is powered by two 9-volt alkaline batteries per side (four, in total); unique circuitry converts the ±9?V to ±100 V without a transformer, yielding an exceedingly quiet output.
