  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.

  Silver / Silver Chloride Refillable Reference Electrode – 6 mm dia. (redox.me)

  It is a compact refillable Ag/AgCl reference electrode equipped with ceramic frit molten into the glass body. This electrode outperforms competing products in terms of mechanical stability, voltage stability and lifetime. In general, the reference electrode is composed of a system of phases, which retain an essentially constant composition, and therefore provides a stable potential by which the working electrode potential can be monitored. The phases present in reference electrodes undergo reversible redox processes at a very high rate, enabling them to rapidly adjust to changes in the solution’s ionic activity, but leaving them sensitive to the passage of large current densities. 

   

  Application note
  This electrode is commonly used with aqueous acidic electrolytes, but due to the low resistance of the frit it can be used with standard non-aqueous electrolytes, as well. The reference electrode should be stored with the rubber plug applied on the tip. Please see the full instruction here. Keeping in the solution may shorten its lifetime (the electrode operates well as long as there is at least ¼ of the solution in the electrode tube). Before use rinse it with deionized water. If air bubbles are present around the porous frit, flick the tip several times to remove them. For cleaning use detergent (dish washing detergent with water), alcohols or acetone and rinse it with deionized water at the end. To re-fill the electrode please follow this article.

  EmStat4 MUX (2-in-1: Potentiostat with integrated multiplexer)

  Gone 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:

  https://www.palmsens.com/product/emstat4-mux/

   

  • 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.
