FC.1ISE.1REF Flow cell for single ion selective electrode with integrated stirring
Read moreThe flow cell with integrated stirring and reduced hydrodynamic noise is designed for the determination of single analyte using one miniature ion-selective electrode (ISE) and one miniature reference electrode with a diameter of 6 mm and length of 60 mm.
Rotation speed of integrated stirrer: 10-4000 rmp.
Miniature ion-selective electrodes and reference electrode were designed for integration into the flow cell for determination of Cl-, K+, Ca2+ and Na+ ions.
In flow mode, the system can operate automatically. The speed of the integrated stirrer can also be controlled by applying the corresponding voltage to the motor, connected to a stabilized source.
The flow cell with one selected ISE can be used for:
- Automatic or semi-automatic measurement of concentration of Cl-, K+, Ca2+ and Na+ ions in various solutions (following prior calibration)
- For continuous measurement of changes in concentration of Cl-, K+, Ca2+ and Na+ ions.

MPH 472 Universal Potentiostat
Read moreThe instrument enables measurement of amperometry, potentiometry and conductometry. Communication with the computer is provided via USB or Bluetooth. This hand-held device is equipped with GPS navigation so the measured data may be enhanced by the exact coordinates of the location where the measurement was made.
Measured data can be stored and later processed in a PC because of the SD card slot incorporation. The ability to record a waveforms or integrate the measure values is enabled. Basic evaluation methods are also implemented – linear and non-linear calibration and standard addition method is available. The influence of the type of oxygen electrode membrane, temperature or gas solubility can be compensated for the measured values.
The measured data are automatically recalculated and displayed in units of current, voltage, concentration (g∙L-1 or mol∙L-1) or saturation. Potentiometric measurement allows connection of pH electrodes and ISE.
Key Properties
- Up to 200 hours of battery life depending on the operating mode.
- Excellent analytical tools (graphs, unit conversions, internal standard method for potentiometry, coulometric titration, 10 Henry’s constants for various redox active gases).
- Power supply and data communication via USB, possibility of connection via Bluetooth.

- Calibration stored separately in the device (possibility of changing the memory card without having to recalibrate the device).
- Possibility of separate calibration for 4 probes for amperometry and potentiometry.
- The possibility of using different temperature sensors (PT100, PT1000, Ni1000, ATC Monocrystals).
- Advanced power management (display sleep and automatic device shutdown can be set according to the user’s preferences

Metal Wire Auxiliary Electrode – 50HX15 0.6/250 mm (redox.me)
Read moreThe metal wire counter (auxiliary) electrode is provided in the electrochemical cell as a current sink to shunt excess current away from the reference electrode. The counter electrode is generally chosen to be inert under reaction conditions, typically platinum, rhodium, palladium, or gold wire. It well fits aqueous (FKM O-Ring) and organic solvent (FFKM O-Ring) electrolyte requirements.
Application note
The metal wire electrode is immersed in the ion-conducting solution as a counter electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the process, the electrode should be washed several times with isopropanol or ethanol and dried under the nitrogen flow. Store the metal wire electrode in the glass vial sealed with O-rings (all included in the package).Specification

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

Working Disk Electrode – PEEK body 6 mm dia., 70 mm long (redox.me)
Read moreThis is a Standard Working Electrode in which a disk of electrode material (glassy carbon, gold, platinum, silver, boron-doped diamond, palladium, titanium, and copper) is embedded into the PEEK body by a compressed PTFE or PEEK sleeve. It well fits aqueous and organic solvent electrolyte requirements. If you need a different disk material, please contact us.
Application note
The disk electrode is immersed in the ion-conducting solution as a working electrode. An electric current is passed between the working electrode and the counter electrode for a certain amount of time. After the experiment, the electrode should be washed several times with ethanol or isopropanol. If the disk electrode was used as a current collector with other electrode material, or when there are visible traces of material absorption, it should be polished down to the mirror surface after the experiment is completed. Store the working disk electrode in the glass tube sealed with an O-ring (all included in the package).
