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.

USB Potentiostat Galvanoplot
Read moreUSB Potentiostat Galvanoplot is a super small, low-cost and affordable device suitable for dedicated volume applications, which is optimized for screen-printed sensor and biosensor applications. It can be used in many other research areas and with other electrochemical sensors, for corrosion measurement, battery and super-capacitors or fuel cells.
It is capable of performing all common Amperometric and Voltammetric electrochemistry protocols (CA, LSV, CV, DPV, NPV, SVW, GAL) and can be used with three electrode (WE/RE/CE) and two electrode (WE/RE-CE) setups. Plug the device directly into an Android mobile device through OTG port for a true on-site analysis experience. It is possible to choose from two types of interfaces allowing direct insertion of the BVT SPE sensors or the use of 3 classical electrodes with 2 mm banana plugs (WE, RE, CE).

Activation furnance for electrochemical sensors
Read moreThe activation furnance is a device used for curing individual sensors of the AC1 type. At a defined temperature (up to 1000 °C) depending on the electrode and sensor materials. When the sensor is cured, the surface of the electrodes is cleaned from surface oxides and organic impurities, which results in regeneration of the sensor or its activation. In this way, for example, old sensors with immobilized enzyme layers can be cured for reuse – see example at the end ot the document.

EmStat4 MUX (2-in-1: Potentiostat with integrated multiplexer)
Read moreGone are the days with too many cables. With the EmStat4 MUX you have a potentiostat and a multiplexer in one! The EmStat4 MUX is a powerful potentiostat, galvanostat and impedance analyzer and supports all popular electrochemical techniques. Its 8 channels allow for sequential measurements, for example eight Screen-printed electrodes, or eight working electrodes in eight different cells. The instrument’s measurements can be highly customized using MethodSCRIPT. The 4 different cell connections available allow for many different setups. When the measurements are finished, you can easily save your results in PSTrace, or export your results to Excel.
More information could be found tought link:

- Integrated 8-channel multiplexer
- Supports 2-, 3- and 4-electrode setup using Sense Lead
- Potential range: ± 3V
- Compliance voltage: ± 5V
- Current ranges: 1 nA – 10 mA
- Maximum current: ± 30 mA
- FRA / EIS up to 200 kHz
Two modes of operation
- Consecutive mode: this mode switches channel when a complete measurement has finished
- Alternate mode: this mode switches all activated channels within the specified time interval of a measurement.
In both modes the unselected Working Electrodes can either be left floating or switched to Ground to keep the specified voltage.
Supports a 2-, 3- or 4-electrode setup
- Connect four electrodes per channel by using the Sense Leads.
- Or connect only three electrodes per channel by internally connecting all Sense electrodes to the Working Electodes in software.
- Do you need to connect only two electrodes per channel? Combine the reference and counter electrode physically on the cable, or with a single click on the PSTrace software.
8 to 128 channels
Is 8 channels not enough? If more channels are required, one or more MUX-R2 can be stacked to the EmStat4 MUX for a total of up to 128 channels.
Script your experiments!
Via the script window of PSTrace it is possible to perform a different experiment on each of the channels sequentially. Alternatively, you can use MethodSCRIPT to fully customize your measurements per channel.
Multichannel or Multiplexer?
To make it easier for you to decide, if a multiplexer or a multichannel device is more suitable for your application, we have created a short explanation of multiplexers and multichannels.
