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.

Connection options
The most selected connection option uses two double shielded D-Sub cables ending in 2 mm banana plugs. As alternatives we can provide a PCB with screw terminals, D-Sub cable ending in ferrules or Screen Printed Electrode Adapter. Each of these cables can be connected to 4 channels, if all 8 channels are used, two cables are needed.

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.
* For this product, we recommend our customers use the Training Service from BVT.
