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

Compact Line systems (2)

Autolab PGSTAT204

PGSTAT204

The PGSTAT204 combines the small footprint with a modular design. The instrument includes a base potentiostat/galvanostat with a compliance voltage of 20 V and a maximum current of 400 mA or 10 A in combination with the BOOSTER10A. The potentiostat can be expanded at any time with one additional module, for example the FRA32M electrochemical impedance spectroscopy (EIS) module.The PGSTAT204 is an affordable instrument which can be located anywhere in the lab. Analog and digital inputs/outputs are available to control Autolab accessories and external devices are available. The PGSTAT204 includes a built-in analog integrator. In combination with the powerful NOVA software it can be used for most of the standard electrochemical techniques.

Autolab PGSTAT101

PGSTAT101

The entry level in the Autolab range of electrochemical instruments, the Autolab/PGSTAT101 in combination with the powerful NOVA software, can be used for most of the standard electrochemical techniques. Autolab/PGSTAT101 is an affordable potentiostat/galvanostat without compromising on quality and specifications, making it an ideal instrument for students and educational purposes.The small footprint allows you to place a high quality potentiostat/galvanostat on a crowded workbench. Analog and digital inputs and outputs for interfacing and controlling external devices are available. The Autolab/PGSTAT101 comes with an internal dummy cell and a built-in analog integrator.

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.

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.
