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).
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
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
