Model 170 – Cyclic Voltammetry Module
MicroLab’s Cyclic Voltammetry Module uses inexpensive screen-printed electrodes and works with the MicroLab FS-528 interface to easily create cyclic voltammograms.
MicroLab’s affordable Cyclic Voltammetry Module uses inexpensive Pine Instruments disposable screen-printed electrodes (ten included). It connects to the FS-528’s Port A multipurpose input, will scan with 1-20 mV steps, and can plot current vs applied voltage or current vs voltage referenced to an Ag/AgCl reference electrode.
All MicroLab data may be exported into Excel for further analysis with a single mouse click.
Demonstration Cyclic Voltammograms may be created with the MicroLab Model 171 CV Electrode Simulator. This unit plugs into the FS-528 Port A in place of the 170 CV unit and simulates a ferricyanide cyclic voltammetry run. It allows change of analyte concentration and modification of all CV parameters accessible in the FS-528 software. Students can experiment with reaction parameters and observe their effect on the CV scan without wasting a screen-printed electrode.
• Voltage (applied potential) vs time (to demonstrate the shape and range of the assigned voltage scan).
• Current to working electrode vs applied potential
• Current to working electrode vs applied potential, referenced to Ag/AgCl reference electrode
• Analysis of potassium ferricyanide
• Analysis of children’s aspirin, acetaminophen
