5. Remove the reagent rotor from the pouch by holding the edges of the rotor. This eliminates
the possibility of fingerprints on the optical surfaces of the rotor.
CAUTION: Inspect the rotor for any damage before use.
6. Use a transfer device to dispense ~100 L of sample into the sample port.
Note: Make sure whole blood samples are homogeneous before adding the sample to the
reagent rotor. Gently invert the collection tube several times before filling the transfer
device. Do not shake the collection tube; shaking can cause hemolysis.
a. Place the transfer device in the sample port (see
and tilt the device until it is perpendicular to the rotor surface (device should touch
the sample port).
b. Fill the sample chamber by transferring the sample slowly and smoothly.
CAUTION: Do not apply excess blood to the sample port. Excess blood may contaminate the
analyzer.
c. A 100 L sample will fill the sample chamber and
form a line between the two triangles printed on
the rotor, as shown in the figure at right. The
reagent rotor is designed to handle up to 120 L of
sample which will partially fill the well just
beyond the two triangles.
Note: If an air bubble is introduced, add enough sample to
fill the overflow area by 1/3 to 1/2. The figure at right
shows sample volumes. Review this diagram before
adding sample to the rotor.
d. Tilt the rotor approximately 45º so that the sample port is higher than the arrows.
This will cause any sample remaining at the sample port to flow into the sample
chamber.
7. Do not spill blood on the bar code ring or reagent rotor. Carefully wipe up any spilled blood
with a lint-free tissue. Ensure that the tissue does not pull any sample back out of the sample
port.
