Gamry Instruments potentiostats

Technical selection of Gamry Instruments potentiostats and galvanostats: Interface 1010E, Interface 5030P, Reference 620, Reference 3020, the 30k Booster, EIS Box and the LPI1010 interface.

Interface 1010E potentiostats

The Interface 1010E works as a potentiostat, galvanostat and zero resistance ammeter. It delivers up to ±1 A in 9 ranges from 10 nA and has built-in EIS from 10 µHz to 2 MHz. The floating design suits autoclaves and pipeline probes, and an RTD input monitors temperature.

Current up to ±1 A
EIS up to 2 MHz
Applied potential ±12 V
Weight 2.4 kg

Interface 5030P potentiostats for single cells

The Interface 5030P is built for single-cell testing of batteries, fuel cells and electrolyzers. It provides up to ±5 A in six ranges from 50 µA, ±6.5 V compliance and built-in EIS to 20 kHz. Two electrometers measure the anode and cathode potentials in addition to the full cell voltage.

Current up to ±5 A
Compliance ±6.5 V
EIS up to 20 kHz
Two electrometers per cell

Reference 620 potentiostats for low currents

The Reference 620 is designed for fast low-current measurements with 11 ranges from 60 pA to 600 mA. Built-in EIS reaches 5 MHz, and noise and ripple stay below 2 µV rms. A thermocouple input and auxiliary I/O serve ancillary equipment, and the floating design suits autoclaves.

Current 60 pA to 600 mA
EIS up to 5 MHz
Applied potential ±11 V
Noise below 2 µV rms

Reference 3020 potentiostats for batteries and electrolyzers

The Reference 3020 supplies ±3 A at ±11 V or ±36 V at ±1.5 A, with current ranges down to 300 pA. Built-in EIS reaches 3 MHz, or 500 kHz on high compliance. Up to eight instruments run on one computer, and the optional 30k Booster raises current to ±30 A.

Current up to ±3 A
Voltage up to ±36 V
EIS up to 3 MHz
Eight ±5 V auxiliary inputs

Reference 30k Booster current amplifier

The Reference 30k Booster extends a Reference 3020 to ±30 A for charge and discharge work. Compliance runs from +20 V through zero to −2.5 V, which allows complete discharge of a cell. EIS reaches 300 kHz with a 20 V/µs slew rate, and the bench unit weighs 16 kg.

Current up to ±30 A
Compliance +20 to −2.5 V
EIS up to 300 kHz
Bench unit weight 16 kg

EIS Box multiplexed impedance instrument

The EIS Box measures impedance on up to eight cells sequentially from 10 µHz to 100 kHz and runs alongside a battery cycler. It comes as EIS Box 5000 to ±5 A or EIS Box 1010 to ±1 A. The 3U chassis fits a 19-inch rack, weighs about 10 kg and connects over Ethernet or USB.

Eight sequential channels
Frequency 10 µHz to 100 kHz
EIS Box 5000 up to ±5 A
Eight 3 m cell cables

LPI1010 interface for battery pack impedance

The LPI1010 measures impedance of battery packs and fuel cell stacks with an Interface 1010E and a bipolar power supply or electronic load. It comes in 10 V and 100 V models with galvanostatic or hybrid EIS up to 100 kHz and 16-bit resolution. Older 1010E units need a factory upgrade.

Cell cables: check and replacement

The cell cable is constantly flexed and exposed to corrosive environments. The blue Working Sense and white Reference leads measure about 260 ohm, or about 403 ohm on the Reference 620, while the green Working and red Counter leads measure 0 ohm. A damaged cable is replaced, not repaired.

Extended 1.5 and 3 m cables

Choosing a Gamry potentiostat: Interface and Reference lines

Gamry Instruments builds potentiostats in two lines: Interface for most voltammetry, corrosion, sensor and single-cell energy work, and Reference for low-current and high-current measurements with a wide EIS range.

The Interface 1010E delivers up to ±1 A with EIS to 2 MHz, and the Interface 5030P targets single cells up to ±5 A. The Reference 620 covers 60 pA to 600 mA with EIS to 5 MHz, while the Reference 3020 supplies up to ±3 A or up to ±36 V.

Systems for batteries, fuel cells and electrolyzers

For currents up to ±30 A the Reference 3020 is paired with the 30k Booster, whose compliance runs from +20 V to −2.5 V. For battery packs and stacks the Interface 1010E drives the LPI1010 in 10 V or 100 V models together with a bipolar power supply or electronic load.

The EIS Box measures impedance on up to eight cells sequentially from 10 µHz to 100 kHz alongside a battery cycler; its 3U chassis fits a 19-inch rack.

Multichannel systems and configuration

Up to eight Gamry potentiostats can be combined into one multichannel system, and up to eight Reference 3020 instruments run on one computer. Channels operate separately, in groups or all at once.

Cell cables are part of the configuration: extended cables come in 1.5 m and 3 m lengths, and the EIS Box ships with eight 3 m cables. The Reference 3020 offers an auxiliary electrometer with eight differential voltage inputs.
