Modular Line potentiostat/galvanostat instruments

Metrohm Autolab offers state-of-the-art instruments for electrochemical research without limitations: the Modular Line.

The Modular Line of instruments consists of a range of instruments to suit any requirements in electrochemical research, from low to high voltage and from low to high current.

These instruments can be combined with a range of modules, thus greatly increasing the possibilities of your electrochemical research.

Two base instruments …

The Modular Line consists of three potentiostat/galvanostat instruments. You can choose the suitable instrument to suit your needs:
  • PGSTAT128N: an entry-level, affordable modular instrument
    (12V/800 mA)
  • PGSTAT302N: a high-performance modular instrument (30V/2A)

These instruments can be interfaced with any external device. And thanks to the powerful NOVA software, you have full control of all aspects of your experiments.

Modular potentiostat/galvanostat instrument for electrochemical applications

… that can be expanded to suit your application

The instruments can be supplied with a range of modules to form the perfect system for your specific research requirements.

For instance, you can add modules to enable Electrochemical Impedance Spectroscopy (EIS), to increase the maximum current, or to increase the sampling rate, and many more.

Special instruments for specific applications

Metrohm Autolab also offers three special instruments. These instruments are based on the Modular Line instruments and are preconfigured for specific applications:
  • PGSTAT302F: instrument for “grounded mode” and “floating mode”. In grounded mode, it can be used with normal electrochemical cells, whereas in floating mode, it can be used with grounded cells or electrochemical cells in which the working electrode is connected to ground (e.g. pipelines, autoclaves, etc.).
  • PGSTAT128 MBA and PGSTAT302N MBA: These instrument versions can be fitted with up to 5 additional bipotentiostat modules (BA), allowing you to use a total of 6 working electrodes in one electrochemical cell sharing a common counter and reference electrode.
