Disassembling the Fluoride Combination Electrodes and
Single Junction Reference Electrode
Note:
Disassembly is usually not required and should not be
done unless a thorough cleaning is required.
1. Tip the electrode so the fi lling solution moistens the O-ring
on the electrode body. Hold the electrode body with one
hand and use your thumb to push down on the electrode
cap to drain the chamber.
2. Unscrew the cap counter clock-wise and then slide the cap
and the spring up the cable.
3. Hold the outer sleeve with one hand and fi rmly push down
on the threaded portion with the thumb and forefi nger to
separate the inner body from the sleeve.
4. Grasp the cone with a clean, lint-free tissue and withdraw
the body from the sleeve using a gentle twisting motion.
Do not touch the reference electrode element (coiled wire
in combination electrode, pellet in single junction reference)
above the cone, it will damage to the reference element.
Rinse the outside of the electrode body and the entire
sleeve with distilled water. Blot dry with a Kimwipe and
allow to air dry if needed.
Reassembling the Fluoride Combination Electrodes and
Single Junction Reference Electrode
1. Moisten the O-ring on the electrode body with a drop of
fi lling solution. Insert the screw-thread end of the electrode
body into the tapered, ground end of the sleeve.
2. Push the body into the sleeve using a gentle twisting
motion until the bottom surface of the inner cone is fl ush
with the tapered end of the sleeve.
3. Place the spring onto the electrode body and screw on the
cap. Refi ll the electrode with fi lling solution.
