Disassembly and Cleaning
For Orion 90-01 and Orion 96-09:
Disassembly is not normally required and is not often
recommended. When the area between free electrode sleeve
and inner cone becomes clogged with sample or precipitate
from filling solution, the chamber can be cleaned by flushing
out with filling solution or distilled water.
1. Holding the electrode upright, wrap around the electrode
body with your palm and place your thumb on the cap.
2. Push with your thumb on the cap will drain solution from
the chamber.
3. If the chamber is not completely cleaned, repeat
the procedure.
4. Refill with Thermo Filling Solution Orion 900001 for
Orion 90-01 or with Orion 900061 for Orion 96-09.
If a more thorough cleaning is required, the electrode can be
disassembled using the following instructions:
1. Tip the electrode so that the filling solution moistens the
o-ring on the electrode body. Hold the electrode body by the
cap with one hand and push the outer sleeve of the electrode
up into the cap to drain the chamber.
2. Unscrew the cap counter clock-wise and then slide the cap
and the epoxy-coated spring up along the cable.
3. Hold the outer sleeve with one hand and firmly push down
on the threaded portion with the thumb and forefinger to
separate the inner body from the sleeve.
4. Grasp the cone with a clean tissue and withdraw the body
from the sleeve with a gentle twisting motion, Do not touch
the AgCl pellet above the cone, it may cause damage to
the pellet.
Rinse the outside of the electrode body and the
entire sleeve with distilled water. Allow to air dry.
Reassembly
1. Moisten the o-ring on the electrode body with a drop of
filling solution. Insert screw-thread end of the electrode body
into the tapered, ground end of sleeve.
2. Push body into sleeve with a gentle twisting motion until
bottom surface of inner cone is flush with the tapered end of
the sleeve.
3. Place the spring onto the electrode body and screw on the
cap. Refill with filling solution. The electrode is now ready
for use.
