Description

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.

Accessories

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.

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.

Software

MultiTrace for Windows

The MultiTrace software gives you full control over the channels of our multi-channel instruments. MultiTrace can be used with multi-channel potentiostats in two different modes; the Individual and Simultaneous mode.

Individual mode

All potentiostats are used independently. Measurements can be started on all channels with one click, or one at a time on individual channels. Each measured curve is shown in its own plot.

Simultaneous mode

All channels run the same measurement at the same time (optionally hardware-synchronized). The measured curves are displayed in a single plot and can be stored together in a single data file or in separate data files.

Software Development Kits

The PalmSens Software Development Kits (SDKs) for .NET can be used with any of our instruments or OEM potentiostat modules to develop your own software. The SDK’s come with a set of examples that shows how to use the libraries.

PalmSens SDKs with examples are available for the following .NET Frameworks:

  • WinForms
  • WPF
  • Xamarin (for Android)
  • UWP
