8/16-Channel Potentiostat for High Resolution Data Logger
The device consists of a combination of an multi-channel potentiostat/converter (BVT Technologies) and an external USB Pico ADC high resolution data logger (Pico Technology).

The data logger can be supplied in two versions: ADC-20 (20 bits, 8 channels) or ADC-24 (24 bits, 16 channels). For detailed specifications, see the attachment at the end of the document. The device allows measurements from up to 8 or from up to 16 independent channels. The basic output signal is a voltage in the range of -2.5 to 2.5 V. All channels are programmable (the output can be concentration, temperature, pressure…).

After connecting the device to a PC with Pico Technology’s Picolog 6 measurement program installed, the voltage [V] can be processed using math channels and directly recorded in real time as temperature, current, resistance, frequency, % and pressure, see measurement example at the end of the document.

For temperature measurement, the device is compatible with resistance thermometers (Ni 1000, Ni 5000, Pt 1000. Power is provided via USB-B, the maximum electrical consumption of the device is 500 mA.

EmStat4X
The EmStat4X delivers high performance in a small footprint. The EmStat4X is a small battery and USB-powered Potentiostat, Galvanostat, and optional Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS).

The EmStat4X Low Range (LR) version is great for applications that require measuring low currents down to picoamps, like (bio)sensor research. The High Range (HR) version is very suitable for applications that need a maximum current of up to 200 mA. The EmStat4X is controlled with PSTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.

More information can be found through the link: https://www.palmsens.com/product/emstat4s/

The EmStat4X LR and HR features include:

Fast EIS support: for running fixed-frequency EIS measurements at a very low interval of around 1 ms.

Auxiliary Port: for connecting to a MUX8-R2 multiplexer, temperature sensor, pH sensor, stirrer control, triggering and more.

iR compensation: to compensate for the iR drop between the Reference electrode and the outside of the double layer of the electrochemical cell.

Bluetooth: for a wireless connection to a PC, smartphone or tablet

11.1 Wh battery: for more than 8 hours of continuous measurements (typical with the LR).

Small borderless display: showing the state of the battery and connectivity.

Two versions

The EmStat4X comes in two different versions:

Low Range: for lower currents and potentials (±30 mA / ±3 V applied / ±5 V compliance)

High Range: for higher currents and potentials (±200 mA / ±6 V applied / ±8 V compliance)

Both versions can be configured with optional EIS/FRA up to 200 kHz.
See specifications for a detailed comparison between the LR and HR.

Hanging Platinum Drop Electrode

The Hanging Platinum Drop Electrode (HPDE) is solid phase alanogy of HMDE.

The drop of liquid Pt at 2000 °C forms a drop of Pt. The surface of HPDE has nearly ideal surface which is impossible to obtain using polishing. HPDE has also spherical symmetry which enables mathematical treatment of its response.
The material is not toxic and it is chemically stable. The only disadvantage is HPDE cleaning, which can be, however, in some cases solved by carefull insertion of the electrode tip to the flame of an alcohol burner.
Thus HPDE can be used as reference electrode for complicated electrochemical studies, where it is necessary to distinguish the analytical signal from the signal generated by surface inhomogenities.

Hanging platinum drop electrode (HPDE) is designed for measurements with thermostated cell TC4, TC5, TC6 and TC9.

SIRE Sensor Cell Set (Sensor with Injectable Recognition Element)

The SIRE Sensor Cell Set consists of a sensor with an integrated non-removable specialised chamber.

The set also contains a syringe which will allow the injection of the recognition element (Enzyme).
The SIRE Sensor Cell uses the concept of soluble enzymes into a reaction chamber separated from the sample by a semi permeable dialysis membrane. The analyte (for example maltose), enters into the reaction chamber by diffusion. The analyte reacts with the recognition enzymes creating H₂O₂ which is oxidized on a screen printed Pt electrode. The current corresponds to the amount of analyte.
