MAINTAINING THE CERAMIC CONDITIONING CARTRIDGE
The Ceramic Conditioning Cartridge consists of an aluminum base that supports a ceramic "strip." The
strip is a white strip of Alumina that is held down by a brass retainer and retainer screw. The ceramic
cartridge may be used up to 50 times before the strip is worn and needs to be rotated or up to 200 times
before the strip must be replaced as described below.
Request replacement parts by contacting your i-STAT support provider and refer to the following i-STAT part

PROCEDURE FOR ROTATING THE STRIP
Note: Rubber gloves should be worn to perform the following procedure.
1. Using a small Phillips head screwdriver, loosen and remove the screw and retainer.
2. Remove the ceramic strip.
Note: The ceramic strip is brittle and should be handled with care to avoid damaging or
contaminating it.
3. Inspect the ceramic strip for damage. Replace if cracked or chipped. CRACKED STRIPS MUST
BE REPLACED BEFORE USING THE CERAMIC CARTRIDGE IN AN ANALYZER.
4. Inspect the aluminum base. Clean if necessary with isopropyl alcohol and soft, lint-free cloth.
Avoid using paper that might leave fibers on the ceramic cartridge which might be carried into
the analyzer.
5. Rotate the ceramic strip to the next orientation (either spin around or flip over).
Note: The ceramic cartridge may be used to perform 25 repairs before rotating or replacing
the strip. The strip may be rotated 3 times before replacing it (i.e., the strip has a total of
4 positions; original position of the strip plus 3 rotations). In other words, a single strip
may be used to repair 100 analyzers – 25 analyzers per orientation of the strip. The 4
orientations are:
1. Initial position
2. The strip rotated by "spinning it" 180 degrees, same side up.
3. The strip rotated by turning it over, now back-side up.
4. The strip rotated by "spinning it" again 180 degrees, back-side still up.
6. Place the ceramic strip in the base, making sure it sits flat in the recess and does not overhang
either edge (i.e., the inner edges adjacent to the strip, not the wider edges back on the body of
the cartridge).
7. Replace the retainer plate and retainer screw.
Note: Over-tightening the screw may damage the threads in the base or crack the ceramic strip.
8. Record the strip rotation in the Use Log.
