==> After obtaining free-flowing blood from a lancet puncture of the finger, or 10μl blood from whole blood from the tube, remove the protective plastic shield from the capillary pipette. (((Holding the capillary pipette slightly above the horizontal, touch the tip to the blood source))) (see the next picture).
==> The pipette will be filled by capillary action.
==> When blood reaches the end of the capillary bore in the neck of the pipette, filling is complete and will stop automatically.
==> The amount of blood collected by the capillary tube is 10 ml.
==> Wipe any blood off the outside of the tip of capillary tube, making sure that the wipes don’t touch the opening of the capillary tube to avoid absorption of blood by the wipes.
Drawing blood into the Unopette capillary tube: A. From a finger puncture; B. From a venous blood sample.
==> Release pressure on the reservoir and remove your finger from the overflow chamber opening.
==> Suction will draw the blood into the diluent in the reservoir
because when you press on the reservoir some air goes out and when you seat the capillary holder to the reservoir opening while your index finger cover the capillary holder opening, the air will not back to the reservoir, but when you release the pressure and remove your index finger from thr openning of the capillary holder, the air will enter to the reservoir through the capillary tube which push the blood into the reservoir and mix the blood with the isotonic solution
==> Squeeze the reservoir gently two or three times to rinse the capillary tube, forcing diluent into but not out of the overflow chamber, releasing pressure each time to return diluent to the reservoir.
==> Close the upper opening with your index finger and invert the unit several times to mix the blood sample and the diluent.
Mixing blood sample and diluent.
For specimen storage, cover the overflow chamber of the capillary tube with the capillary shield.
