Compact Line potentiostat/galvanostat instruments

Space is becoming increasingly scarce in modern research laboratories. Smaller instruments thus allow you to accommodate more instruments on the available space and expand the range of experiments and measurements in your lab.

This is why Metrohm Autolab offers two compact, space-saving instruments:

  • the PGSTAT101, a compact entry-level potentiostat/galvanostat and
  • the PGSTAT204, a space-saving modular instrument.

Key features

  • Compact and easy to carry 
  • Competitively priced
  • Designed to interface to any external instrument
  • Flexible software control
  • Complete range of accessories

Small, lightweight, and economical

With a footprint of just 9 by 21 cm (3.5 by 8.3 in) and 15 by 26 cm (5.9 by 10 in) the Compact Line instruments take up very little space in the lab.

In addition, weighing just 2.1 kg (4.6 lbs) and 4.1 kg (9 lbs), these instruments are also easy to carry, making them the ideal routine all-round potentiostats/galvanostats in your lab.

Thanks to the small footprint and the low cost of ownership, the Compact Line instruments are the economical choice for electrochemical research.

No compromising on quality and functionality

The reduced size is not at the expense of quality. These small instruments come with analog and digital inputs/out for interfacing Autolab accessories and external devices.

Like all Autolab instruments, the Compact Line potentiostats/galvanostats  are controlled with the powerful NOVA software. This gives you complete flexibility to devise and design your experimental procedures.

PGSTAT101: a small instrument for most standard electrochemical techniques

This small, lightweight, and affordable potentiostat/ galvanostat is ideal for most basic electrochemical research applications. Thanks to the on-board integrator, you can also perform coulometric measurements and current integration cyclic voltammetry.

PGSTAT204: compact modularity

The PGSTAT204 offers you everything you need in one small-sized instrument.

The base potentiostat/galvanostat has a compliance voltage of 20 V and a maximum current of 400 mA, which can be expanded to 10 A with the BOOSTER10A option. Furthermore, you can add new functions to it at any time with one additional module, for example the FRA32M electrochemical impedance spectroscopy (EIS) module.
