Amel - Model 4330 -Voltammetric Analyzer
The ultimate system for trace analysis which can be equipped with Hanging Drop Mercury Electrode, Rotating Disk Electrode or Static Electrodes. The range of available techniques and the complete set of working electrodes allow for the widest range of analysis.
The system has a built-in stand which can even accomodate PMMA cells for screen printed electrodes. Flow measurements are performed with dedicated cell. For the call of automation, the system can be integrated with Model 235 Automatic Dispenser, reducing the time spent in the addition of standards. VApeak softaware fully controls the unit.
