More Details

Below are additional details regarding the capabilities of the Reference 600+ potentiostat. Each bullet point contains a list of the type of techniques available for the instrument to run.

  • Physical Electrochemistry  - Techniques such as cyclic voltammetry, chronoamperometry, and chronopotentiometry and derivatives of these techniques.  
  • Pulse VoltammetryTechniques such as pulse voltammetry, square wave voltammetry, and associated stripping techniques such as anodic stripping voltammetry.  
  • DC CorrosionRun standard DC corrosion tests such as polarization resistance, potentiodynamic, cyclic polarization, and galvanic corrosion in addition to a number of others.
  • Electrochemical EnergyTest single-cells and stacks of various batteries, fuel cells or supercapacitors. Includes charge, discharge, cyclic charge-discharge techniques, potentiostatic, galvanostatic, self-discharge, leakage rate, and read cell voltage.
  • Electrochemical Signal Analyzer -  Designed specifically for the acquisition and analysis of time-dependent electrochemical noise signals. Cell voltage and current are continuously monitored at rates from 0.1 Hz to 1 kHz. A full featured set of analysis tools provides powerful analysis features such as statistical analysis, detrending, impedance spectra, and histogram analysis.
  • Electrochemical Frequency ModulationA non-destructive corrosion rate measurement technique. It allows for measurement of the corrosion rate without prior knowledge of the Tafel constants. In addition, the technique determines the Tafel constants and provides 2 internal validity checks.

We also have our unique power-leveling multisine technique that improves signal-to-noise across the spectrum. On the analysis side, it provides tools for fitting spectra to equivalent circuit models, Kramers-Kronig transform for data validation and a graphical model editor. Our software even includes a script for EIS simulation.

Good, capable and portable potentiostat.

Rating: 4.7 4.70 Out of 5 Stars

Organization: IMRE, A*STAR

Application Area: Electrochemical measurements, batteries, electrocatalysis

"Reference 600+ is reasonably portable, ideal for in-situ experiments. Software is easy to use, although the UI is a bit lacking compared to other brands, for example it couldn't modify your settings on the fly. But, there is an option of customised scripting that expands the experiment possibility if you're willing to invest some time to learn to code. Price is slightly more affordable than other potentiostat with similar capabilities. After sales is reasonable, queries and service request through distributor network is usually prompt, but repairs can take a while if the parts or your hardware need to be shipped to the US."

This equipment gave insights I couldn't get via coupon testing. I use it daily!

Rating: 5.0 5.00 Out of 5 Stars

Organization: Anonymous Company

Application Area: Corrosion testing.

"Historically we only leveraged coupon testing. I came in contact with the Gamry equipment after a Penn State corrosion short course. I leveraged a nearby corrosion lab to generate some results and concluded a few months later this equipment definitely has the right capability for my needs, of fast and predictive corrosion understanding. The order and set up in our lab went really smoothly and happened in partnership with the vendor over 3 days of training. Following the training the supplier offered a question and answer period of two weeks to ensure all went fine, and I submitted a few questions and received great help. Given the great partnership with the vendor the implementation, ease of use and after sales support turned out to be most successful. I wish I had bought and implemented it earlier."
