Shake speed – Define the shake speed Off, Low, Medium, or High.
●
The default is Off. The shake speed setting is effective only when the
soak time is > 00:00.
Caution Ensure that the liquid does not spill at the shake speed and
volume settings in use.
Wash mode – Define the wash mode. The default is Plate mode.
●
Plate – All selected strips are processed before the next cycle.
•
Strip – Each selected strip is processed the number of cycles
•
defined before moving to the next strip.
Strip over mode – Define the strip over function. The default is
●
No.
No – All selected strips are processed as fast as possible.
•
Yes – If Yes is selected, unused strips are processed dry. The
•
time parameters are measured during the first protocol run.
The wash head stays above unused strips for as long as it
takes to process each selected strip. This selection is
recommended when the timing for washing strips is critical.
You can maintain the time between cycles constant with this
option. It is recommended to carry out a dummy run before
the actual samples. Refer to Figure 6–37.
Aspirate mode – Define the aspiration mode Normal, Sweep 2, or
●
Sweep 3. Sweep is allowed for 96-well plates with flat wells. The
default value depends on the wash head type or well shape. Refer to
Figure 6–38.
Normal – There is one aspirate position in the center of the
•
well.
Sweep2 – Aspirates in two different positions across the
•
bottom of the well.
Sweep3 – Aspirates in three different positions across the
•
bottom of the well.
Aspirate height – The aspirate height ranges from 0 mm to 14 mm
●
in 0.1 mm increments. The default height varies according to the
plate type and well shape (see Table 6–6 on page 70). The zero
height from which the aspirate height is defined is the lowest level of
a plate when the plate is properly placed on the plate carrier. Refer
to Figure 6–40.
Caution Too high an aspirate height increases the residual volume.
