CEc Calomel Electrode Conic
The calomel electrode (CEc) is a reference electrode based on the reaction between elemental mercury and mercury(I) chloride. The aqueous phase in contact with the mercury and the mercury(I) chloride (Hg2Cl2, “calomel”) is a saturated solution of potassium chloride in water. The electrode is linked via a porous frit to the solution in which the other electrode is immersed. This porous frit makes liquid junction. Calomel electrode (CEc) is designed for measurements with thermostated cell TC4, TC5, TC6, TC9.
pH Electrode ConicRead more
pHc Electrode are used as sensors for potentiometric determination of H+, respective H3O+ activity, expressed in pH units. Conic electrodes are applicable to all commonly used measuring apparatus with inner resistance of 109 or more. Electrode is designed for measurements with TC4, TC5 and TC6 glass cell.
RCEc.R* Reference Classic Electrode ConicRead more
RCEc is a glass hollow tube with silver or silver covered by silver chloride wire inside. The tube is hollow with the hole in the wall for inserting KCl solution. Hole is covered by a rubber band. Reference classic electrode (RCEc) is designed for measurements with glass cell TC4, TC5, TC6, TC9.
Standard connection is with a 2 mm banana connector.
Connector or banana plug colour is blue.
WCEc.W*.D* Working Classic Electrode ConicRead more
WCEc is a glass tube with a Pt or Au wire inside. Only circle glossy area of the metal wire is outside the glass tube. Standard connection is with a 2 mm banana connector. Connector or banana plug colour is red. Working classic electrode (WCEc) is designed for measurements with TC4, TC5, TC6, TC9 glass cell.
Hanging Platinum Drop ElectrodeRead more
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.
