Plastic 'Leak Free' Microminiature Combination Electrodes

Plastic 'Leak Free' Microminiature Combination Electrodes

The AMANI ‘Leak Free’ series of non-glass, micro pH electrodes are the latest development in our combination (built in reference) pH electrode line. The new technologies used in these electrodes provide superior sensitivity and stability. The ‘Leak Free’ non-porous reference junction eliminates the problems of clogged junction and adsorption of proteins and surfactants. They also have high resistance to chemical including hydrofluoric acid solutions.

With tip diameters starting as low as 650 µm, they are one of the smallest combinations pH electrodes on the market today. The new ‘DUCK HEAD’ design of the AMANI IV has been developed to offer complete protection for the electrode’s tip during insertion without compromising the electrodes performance. The electrode is built into a custom 18.5 ga (1.2 mm) needle and can be used to measure the pH of solid samples such meats, fruits, and vegetables without sample preparation. Custom configurations of the AMANI series of pH combination electrodes are also available, please contact Harvard Apparatus Technical Sales Department for further details.
