Dispense height end
– The dispense height end ranges from 0 mm
to 20 mm in 0.1 mm increments. The default is
17.0 mm
. Refer to
Figure 6–40.
Note
Because aspiration is on during dispensing, the end volume in the
well depends on the dispense height. If the liquid level in the well
during dispensing reaches the wash head tip, then excess liquid is
aspirated.

●
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.
A Cell dispense step fills the wells with liquid dropwise. Refer to “Cell
wash” on page 71.
The
Cell dispense
step has the following parameters:
●
Buffer source
– Define the buffer source channel A, B, or Rinse.
The default is
A
.
●
Dispense volume (μl)
– The dispense volume range is 50 μl to
400 μl in 10 μl increments. The default value is
250 μl
.
●
Dispense height start
– The dispense height start ranges from
0 mm to 20 mm in 0.1 mm increments. The default is
14.0 mm
.
Ensure that the value fits the plate in use. Because dispensing starts
from a lower level in a well and ends at a higher level, the start
height should be lower than or equal to the end height. Refer to
Figure 6–40.
