Uniscan has announced the introduction of the RC10V rotator controller, an accessory specifically aimed at electrode rotator users.
Corrosion processes under extreme environmental conditions such as turbulent fluid flow can be studied with a rotating cylinder electrode (RCE).
The addition of the RC10V controller allows the rotator to be controlled remotely from the Uniscan Instruments range of potentiostats (PG580, Bistat 3200 and PG580RM).
Support is included for a range of manufacturers' instruments.
Application areas include: erosion-enhanced corrosion resistance studies; structures and activity of nanoparticles; RDE and RRDE electrodeposition studies; catalysts for mixed-reactant fuel cell; and electrochemical kinetics studies.
The RC10V accessory connects the Uniscan potentiostat (models PG580, Bistat 3200 or PG580RM) to the electrode rotator.
The rotator speed can then be set directly in software using the Rotator Velocity experiment included with the controller.
The software experiment sequencer provides a versatile mechanism to implement complex automatic experiments.
An example sequence supplied with the controller implements a completely automatic Levich experiment and analysis.
Alternate steps in the sequence set the rotational velocity and perform voltammetric experiments.
The sequence is completed with the Levich analysis experiment step.
This extracts data from the voltammograms and plots the linear regression response.
The diffusion coefficient is then calculated automatically from the response, thereby removing lengthy data extraction and calculation procedures normally associated with this data analysis technique.
