1. The drop needle dispenses a drop of the sample on a slide. It dispenses the rest of the
sample into the drop needle rinse bath and then is rinsed with rinse.
2. The smearing assembly wedge and smearing ribbon create the smear using the
surface tension of the blood. The wedge is positioned on the slide before being
brought into contact with the blood, waiting for the blood to migrate along the
wedge. The waiting time, drop size, smearing speed, and angle of the wedge are all
user-adjustable.
The system then pulls the slide back, producing the smear.
After smearing, the system raises the smearing head and the smearing tape moves to
ready a clean section for the next slide.
3. The slide enters the printer, which can print patient demographics or other
information directly on the slide.
4. After printing, the slide moves into the verticalizer, which transfers it to a staining
well or directly to a rack as required.
5. If staining is required, the slide moves into the stainer, a rotating tray containing 32
staining wells. A needle plate supports needles at adjustable locations to dispense
liquids into the wells or to aspirate liquid from the wells. The slide is stained
according to the staining method in use.
6. Once staining is complete, the slide is transferred to a rack and processing is
complete.
