Warning!
You should wear gloves when filling acella sample carriers, as fingerprints on the glass
may result in incorrect measurements.
When drawing up the sample liquid, make sure that no air bubbles form in the pipette
tip.
3. To fill the acella sample carrier, use a laboratory pipette set to the volume
that is printed on the acella sample carrier.
4. Place the acella on a clean surface and hold the sample carrier on the
opposite side of the sample chamber. If you can read the name “acella” in the
correct orientation, the opening of the sample chamber will be located on the
upper side of the sample carrier.
5. Place the pipette diagonally at the opening of the measuring chamber within
the semicircular boundary (Figure 21).
6. Pipette the volume printed on the sample carrier (Figure 21) slowly into the
semicircular boundary in the direction of the sample chamber.
Figure 21: Inserting the acella adapter and filling the acella sample carrier.
Left: The appropriate adapter for acella is adapter 01.
Centre: Filling the acella sample carrier with the sample fluid.
Right: Correct orientation of the acella sample carrier when being inserted into the device
(coloured square on the lower right-hand side).
Warning!
When filling the sample chamber, be careful not to overfill it, as sample fluid may
escape from under the cover glass if the capacity of the sample chamber is exceeded.
The sample chamber automatically fills up with fluid as a result of capillary forces. The
microscopic measurement is carried out in the lower part of the sample chamber;
therefore, for a successful measurement the chamber should be filled up to the
minimum mark. If air bubbles have formed in this part of the chamber, you can position
the acella sample carrier and gently tap the bottom edge on a hard surface. If the air
bubbles cannot be removed from the lower part of the measuring chamber, a new
sample carrier must be filled. Air bubbles in the upper part of the measuring chamber
are not a problem, as no measurement is carried out in this part.
