Electrode Storage
Orion 90-01
The Orion 90-01 Reference Electrode may be stored in its filling
solution between sample measurements (up to two hours).
For short periods of time (up to one week), the Orion 90-01
should be stored in filling solution. Fluoride standard (0.01 M)
or 100 ppm are acceptable storage solutions. The solutions
inside the electrode should not be allowed to evaporate
causing crystallization.
For storage longer than one week, drain the reference electrode,
flush the inside with distilled water, and store dry.
Orion 94-09
The Orion 94-09 Fluoride Electrode should be rinsed thoroughly
and stored dry in the air at all times. When storing for long
periods of time, replace the cap to protect the sensing element.
Orion 96-09
The solution in the Orion 96-09 Fluoride Combination Electrode
should not be allowed to evaporate, causing crystallization.
For short periods of time between sample measurements,
and up to one week, store the electrode in least fluoride
concentration standard.
For storage longer than one week or for an indefinite period of
time, drain the electrode, flush the inside with distilled water,
and store dry with the cap to protect the sensing element.
