pH electrodes

Storing the electrodes

Electrodes should always be stored in a storage
cap which contains a few ml of electrolyte solution
(re-filling solution). Different electrodes require
different electrolyte solutions which are included in
our range of accessories.
Electrodes with liquid reference electrolytes can
also be stored, only in an emergency and for a
short time, in an open container which contains a
neutral to slightly acidic solution. Electrodes with
gel electrolyte should always be stored in 3 molar
KCI in order to avoid the loss of electrolyte
solution.
All electrodes should be stored in an upright
position so as to ensure that the electrolyte
solution does not pour out of the refill opening.
Electrodes that have been stored in dry conditions
show unstable pH values. Should an electrode
have dried out, it can be regenerated overnight in
water.
