Power Potentiostat / Galvanostat

The Model 1100B series power potentiostat/galvanostat is designed for electrochemical applications that require relatively large current and high compliance voltage, such as battery, corrosion, electrolysis, and electroplating. The current range is 2 A. The compliance voltage is 25 V. The instrument contains a high speed digital function generator, a fast data acquisition system, filters for the current signals, iR compensation circuitry, a potentiostat, and a galvanostat (Model 1140B). The potential control range is 10 V. The function generator can update at a 10 MHz rate, and the maximum sampling rate is 1 MHz at 16-bit resolution. The 1100B series is capable of measuring current down to tens of picoamperes. The steady state current of a 10 μm disk electrode can be readily measured without external adapters. The instrument provides very wide dynamic range on experimental time scales. For instance, the scan rate in cyclic voltammetry can be up to 1000 V/s with a 0.1 mV potential increment or 5000 V/s with a 1 mV potential increment. The potentiostat/galvanostat uses a 4-electrode configuration, allowing it to be used for liquid/liquid interface measurements and eliminating the effect of contacting resistance of connectors and relays for high current measurements. The data acquisition systems allow an external input signal (such as spectroscopy signals to be recorded simultaneously with electrochemical data).

The model 1100B series is the upgrade from the model 1100/1100A series. The instrument utilizes FLASH memory, allowing instrument updates to be distributed by e-mail instead of the shipment of an EPROM chip.

The 1100B series has a USB port (default) or a serial for data communication with the PC. You can select either USB or serial port (but not both) by changing the switch setting on the rear panel.

A 16-bit highly stable bias circuitry is added for current or potential bias. This allows wider dynamic range is ac measurements. It can also be used to re-zero the dc current output.

We provide several different models in the 1100B series. The following table compares the different models. Other than what is listed, the specifications and features of these models are identical. Models 1100B/1110B are basic models. while Models 1140B is more advanced models with a galvanostat.
