Our multi channel potentiostats are designed for
the most demanding users who want quality and
high productivity without compromising on cost.
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.
Standard packaging includes a shielded cable for each channel with connections for a working, a counter and a reference electrode by means of 2 mm banana connectors (crocodile clips included), a USB cable and an AC adapter. The four channel MultiEmStat3 will be delivered in a small housing which is USB powered for extra mobility.

The following techniques are supported by MultiEmStat.
These methods can all be used in their stripping modes which are applied for (ultra-) trace analysis.
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.

MultiTrace is our standard software for multichannel instruments. It is based on PSTrace and comes standard on a CD as well as download. The channels can be controlled all at once or get individual commands. Also the scripting feature can be used individually or for all channels.
