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.

AC1.GP. Electrochemical sensor with a working electrode of guaranteed purity
Read moreBasic amperometric three-electrode sensor with patented structure made by thick film technology.
Dimensions: 25.40 mm x 7.26 mm x 0.63 mm
WE material: gold, platinum, silver, copper, iron, nickel, cobalt, chromium, tantalum, irridium, rhenium, magnesium, palladium, zirconium and others
*Selection of sensor electrode materials other than those listed above is possible upon agreement with the customer.
The sensor is made on a corundum ceramic base. Working, reference and auxiliary electrodes are applied to this surface. Working, reference and auxiliary electrodes are made of different materials. At the end of the sensor there is a contact field that is connected to the active part by silver conductive paths that are covered with a dielectric protective layer. The working electrode of the sensor with a diameter of 2 mm is made of a material of guaranteed purity of up to 99.99 % depending on the selected material– standard layer thickness 0.0125 mm.
We also offer a working electrode made of polished gold AC1P.W*.R*, with homogenous surface with roughness less than 1 µm.
We also offer activated graphite sensors on customer request.

EmStat4X
Read moreThe 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.Always a backup
The EmStat4X is equipped with 500 MB internal storage memory for storing your measurements as a backup. All internally stored measurements can be browsed and transferred back to the PC easily using the PSTrace software for Windows. Your data is always with your instrument wherever you take it.
