The MultiEmStat is a versatile multi 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.
MultiEmStat3 is available as four channel in the small housing and 8 and 12 channel in the larger housing.
MultiEmStat3+ is available as 4, 8 or 12 channel and always comes in the larger housing.
