Model 1285 Potentiostat/Galvanostat
The model 1285 combines Solartron Analytical
measurement hardware with highly respected CorrWare for Windows™software.
In conjunction with a standard PC, a complete spectrum of DC
measurement techniques can be applied with unprecedented ease:
- open circuit
- potentiostatic
- galvanostatic
- potentiodynamic
- galvanodynamic
- cyclic voltammetry
|
- potential square-wave
- potential scan/hold
- potential stair-step
- galvanic square-wave
- galvanic cycle
- electrochemical noise
|
Complex experiments can be set up, stored and
repeated at the click of a mouse. Using the scanner facility,
multiple sequences can be repeated indefinitely without further
intervention. Data can be analyzed in a wide variety of display
formats, and you can even calculate corrosion rates using automatic
Tafel curve fit routines.
Simultaneous current and voltage measurement
Solartron’s patented pulse width conversion technique gives
the 1285’s voltmeters unequalled accuracy, stability and linearity
right across the range - perfect for work with low conductivity
electrolytes, for example. In addition, unlike many potentiostats,
the 1285 has two “5x9” digital voltmeters enabling true
simultaneous current and voltage measurements to be made - essential
for measuring electrochemical noise.
Floating 2, 3 or 4 terminal measurements
Use 2 terminals for general electrochemistry, 3 for corrosion
investigation, or all 4 for measuring single battery cells or ion
transport across membranes. Whatever your application, for total
floating flexibility - working on buried structures, pipelines,
storage tanks or autoclaves, say - there’s only one answer: the
1285.
Unrivalled resolution
With resolution down to 1µV for the reference electrode and 1pA
for the working electrode, the Solartron 1285 outperforms all other
potentiostats. It has to be the favorite for low signal applications
such as coatings and inhibitors, and with ±14.5V polarization
voltage and ±2A polarization current for the counter electrode, the
1285 is first choice for batteries and fuel cells.
If you require the ability to perform AC
measurements using an FRA, then please consider our model 1287A
Potentiostat/Galvanostat instead. This offers all the
capabilities of the 1285 but with additional support for AC
techniques.
