Step 2: Roll Tube Between Fingers to Mix
Gently roll tube between fingers at least 10 times
or for at least 5 seconds, keeping unsealed end
slightly above horizontal (D). Proceed promptly to
Step 3.
Step 3: Insert Float
With 424240 Tray – Slide unsealed end of tube over
tip of pre-positioned float (E1) and push until float is
inside tube as far as possible. Gently lift closure end
of tube until float releases from its tray slot. Raise
unsealed end of tube slightly above horizontal to
prevent float from falling out. If necessary, press
end of float against clean surface until float is inside
tube. NOTE: Never touch floats with fingers or
gloves. Use forceps to handle loose or dropped
floats.
With 424237 Box – Using forceps supplied with
analyzer, pick up float from well. Insert forceps-held
float into unsealed end of tube (E2). With forceps,
tap float into tube. Never touch float with fingers
or gloves.
Note: After inserting float, tubes can be held for
centrifuging provided they are stored vertically,
closure down in workstation. A maximum of
15 minutes is allowable between insertion of float
and centrifugation.
Step 4: Centrifuge for 5 Minutes
Place blood tubes in centrifuge. Spin down
according to instructions in centrifuge manual.
When centrifugation is complete, promptly remove
tubes.
Time Delay Between Completion of
Centrifugation and Tube Reading: Centrifuged
QBC tubes are stable for up to 4 hours prior
to reading, if stored vertically (closure down) in
workstation, away from heat and intense light.
IMPORTANT:
• Excessive heat may disturb cell interfaces in
centrifuged blood tube. Avoid picking up or
handling spun tube below plasma column.
Do not place centrifuged tubes on warm
surfaces or under intense light.
• Do not leave blood tubes on rotor after
centrifugation. Remove and read
immediately, or temporarily store in vertical,
closure-down position.
• Do not twist or move tube closures after
centrifugation.
