The pH measurements of the buffer solution used as supporting electrolyte were performed in a combined glass electrode
(ION, model pHB - 500) connected to a digital pH meter (Elektron, model E65-1).
At first glance, this connection may not be obvious; however, it is the fundamental heuristic behind the glass electrode
The glass electrode
is likely the most common chemical sensor that is encountered in a laboratory.
These sensors should have a flat glass electrode
and flat surface porous Teflon reference.
com), has created a more rugged version of the standard glass electrode
Joseph's home-made apparatus featured a glass electrode
and a sensitive galvanometer, both too delicate to withstand the rough field conditions under which they were used.
After piercing the neuron with a microscopic glass electrode
, they stimulated the cell with pulses of current and recorded its behavior.
The new glass electrode
technology we are offering, for example, has already been proven to last twice as long in harsh environments as conventional electrodes," said Ken Brown, vice president and general manager of Foxboro Measurements and Instruments.

A pH electrode, such as the most commonly used glass electrode
, shows neither SPAN error when it produces 59.
The domed glass electrode
is for the harshest applications: temperatures up to 250 F and extreme chemical concentrations.
The response time of a metal oxide pH sensor is faster than a conventional glass electrode
with operating temperatures of up to 121 C (250 F) and 100 psi.

For manual determination the Metrohm 691 meter with a combined glass electrode
assembly, Dosimat dispensing unit and titration stand are used, whilst for automated analyses the Titro processor or Titrino ranges of titrators are recommended by Metrohm UK Ltd of Unit 2, Topangel, Buckingham Industrial Park, Buckingham, tel: 0128 082 4824.
