Dual PicoStat

The Dual PicoStat is a two channel high sensitivity potentiostat suitable for use with carbon fiber and ultramicroelectrodes for the monitoring of low current signals (down to picoameperes). It is commonly used for in vivo monitoring of dopamine by amperometry.

The Dual PicoStat is designed exclusively fore use with an Edaq e-corder unit. The 4-channel e-corder 410 is recommended.

There are two potentiostat channels which enable the unit to also be used as a bipotentiostat (two working electrodes with a common reference and auxiliary electrode) so that dopamine levels can be monitored at two separate locations. Alternatively it can be used to perform duplicate experiments with separate samples, each with a working, reference and auxiliary electrode.

It can also be used as a 4-electrode voltage clamp (with two current passing and two voltage sensing reference electrodes) for studies of ionic transport across membranes or immiscible interfaces.

The Dual PicoStat is electrically isolated and is resistant to interference from neural stimulators, and ground loops. It is DC powered and can be used inside Faraday cages if required.
