Diluent/Sheath Syringe
1. Locate the Diluent/Sheath Syringe (refer to Figure 9.17). Note that the plastic
barrel of this syringe has four vertical edges, two of which fit into grooves on
the holding block, and a circular plastic flange which also fits into a groove
on the holding block.
2. Grasp the plastic tube fitting at the top of the syringe that attaches to the Luer
Lock. Carefully turn the Luer Lock on the syringe clockwise to release it
from the fitting. Use the lint-free pads to absorb excess reagent.
3. Grasp the syringe barrel below the Luer Lock with one hand. With the other
hand, grasp the syringe plunger below the metal band. Pull and twist one side
of the syringe to remove it from the snap-in holding block.
4. Note the liquid level in the syringe so that it can be refilled after cleaning to
approximately the same level.
5. Dispense the reagent into a sink or other appropriate waste container.
NOTE: Do not pull the plunger out of the barrel. Also, do not push or pull
on the plunger when the syringe is dry, as it may damage the
plunger. Avoid touching the plunger, because oil from the fingers
may cause it to move erratically.
6. Immerse the tip of the syringe in the container of deionized water.
7. Aspirate deionized water into the syringe until it is full, and dispense the
water into a sink or other appropriate waste container. Repeat this step several
times to thoroughly rinse the syringe.
8. Refill the syringe with Diluent/Sheath reagent to the level noted in Step 4.
