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. A MultiEmStat channel is capable of the full range of techniques an EmStat can offer, i.e. (pulsed-) amperometric measurements as well as voltammetric measurements like linear sweep, cyclic voltammetry, differential pulse and square wave voltammetry.
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.
All supported techniques for MultiEmStat:
Voltammetric techniques
- Linear sweep voltammetry (LSV)
- Differential pulse voltammetry (DPV)
- Square wave voltammetry (SWV)
- Normal pulse voltammetry (NPV)
- Cyclic voltammetry (CV)
Technique as a function of time:
- Amperometric detection (AD) (Chronoamperometry)
- Pulsed amperometric detection (PAD)
- Multiple pulse amperometry (MPAD)
- Open circuit potentiometry (OCP)
- Multistep amperometry (MA)
Housings
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.
