FC.1ISE.1REF Flow cell for single ion selective electrode with integrated stirring
The 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

Hanging Platinum Drop Electrode
Read moreThe 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.
