Ametek VS-SECM (

DC and AC) Scanning Electrochemical Microscope - Combines accuracy of position and measurement for high-resolution localized electrochemistry

The VersaSCAN Scanning Electrochemical Workstation is a platform for performing electrochemical measurements. This system integrates positioning technology and measurement instruments to provide local information. Traditional electrolysis experiments measure an average response over the entire electrode and electrolyte interface. Samples are rarely homogenous; they often consist of local sites of passivate or active nature, as well as sites of anodic or cathodic character. This need to investigate localized phenomenon led to the emergence of scanning probe electrochemistry.

VersaSCAN uses piezoelectric motors to drive the stages on all axes. Piezo materials are high-precision, accurate and repeatable but over small distances. We use them to drive stages; therefore we reach a combination of scan area and scan resolution that is unmatched by other AFMs. Other AFM designs don’t move with the same resolution. Our service includes installing your instrumentation, assembling it on site, leveling it with precision bubble levels, testing it on a sample to verify performance and training you in how to use it.
