The instrument potentiostat/galvanostat 302 M Autolab together with the potentiostat/galvanostat Autolab12PGstat represents the state of the most comprehensive and advanced electrochemical instrumentation and can be used for all electrochemical applications. In fact, one of the most important features of this tool electrochemical Autolab is modularity. The basic instrument is a potentiostat/galvanostat, then with all the basic electrochemical techniques such as cyclic voltammetry, differential pulse voltammetry, square wave voltammetry, coulometry, chronoamperometry, etc. The instrument can be further adapted to your needs by adding one or more of the modules available in a manner to increase the possibilities for application in various fields. The base module 302N is implemented with a module FRA 32M for electrochemical impedance measurements that allow electrochemically characterize the materials in a more general manner possible, for example, to assess the changes of surface or to study interactions with biological molecules and reactions and kinetics electron-transfer and not only, as is well known, in studies of corrosion. The other module that implements and completes the system is the module EQCM. Using this module EQCM, one determines the ratio between the mass change of the surface of the electrode during an electrochemical reaction and the total charge involved. This technique is very useful in the study not only of redox reactions or reactions of electroplating, but also to assess both the operation of sensors and biosensors, the variations introduced on the electrode surface during the operation of the sensor, but also to follow changes in the biological material used in the case of a biosensor. The management software NOVA allows you to track and monitor all electrochemical techniques and allows for sophisticated analysis of experimental data and simulation. The potentiostat/galvanostat 910 PSTAT portable mini is small, compact and easy to use and allows you to use all the basic electrochemical techniques, mentioned above. They used disposable screen-printed electrodes (Screen Printed Electrodes SPE), so that it is possible to easily work, even in conditions other than the laboratory, for example for measurements in the field and in real situations as in the food industry. The Software PSTAT is very intuitive, but provides all the basic techniques necessary and can be easily used even by non-experts and/or not skilled people. The 910 PSTAT Mini is powered via the USB connection and a dummy cell is also provided. The dimensions are 80 x 54 x 23 mm3 (weight 94 g).
