HydroFlex
Mercury free Electrodes
Now there is a real alternative to measure electro chemical potentials without using the toxic mercury:

The hydrogen reference electrode HydroFlex made by Gaskatel GmbH.

HydroFlex can be used instead of mercury-,cadmium- and any other reference electrodes. This is very usefull for the battery- and the galvanic industry, laboratories as well as Universities.

Dimensions It is as small as a pencil and thereby very handy. Total length is 12 cm, the shank diameter is 8 mm.
Material: The head is made of resistant plastic (PMMA), the shank is PTFE.
Working temperature: The PTFE shank can be used at solution temperatures of up to 210° Celsius. The ambient temperature of the head is restricted to 50 °C.
Measurement solutions: HydroFlex can be used in different solutions. In contrast to other reference electrodes like for example Hg/HgO- and Ag/AgCl-electrodes the HydroFlex can be used in acids as well as in lyes.
Measurement access of potentiometer: May be chosen with high-resistance or low-resistance.
Further advandages: There is no fluid electrolyte inside of HydroFlex. Thus you can use HydroFlex without an additional electrolyte bridge: An affect by impurities or precipitation is not possible.

Because of the internal H2 supply there is no more need for an extra hydrogen bottle. HydroFlex is supplied with hydrogen by a button cell. This hydrogen source can be exchanged in a few seconds.

HydroFlex does not simply reduce high costs but is also handy and uncomplicated to use. Furthermore it is untoxic and consequently an ecologically-friendly alternative to conventional measurement methods.
