MultiEmStat
The MultiEmStat is a versatile multi-channel potentiostat with 4, 8 or 12 independent EmStat potentiostats. The channels can perform experiments independently of each other.
The MultiEmStat is conveniently connected by means of a single USB connection and controlled by MultiTrace. Each potentiostat has eight (EmStat3) or nine (EmStat3+) current ranges: 1 nA to 10 mA/100 mA with a resolution of 1 pA at the lowest current range and can automatically select the optimal current range.
Galvanic Isolation
The MultiEmStat can optionally be equipped with galvanic isolation (G.I.) for each individual channel. In this case each channel has its own floating ground.
