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.
