Dispense to Waste task parameters

Override dispense flow rate
from liquid class
The option to override the dispense velocity
specified in the liquid class. Selecting this option
enables you to specify a value for the dispense
flow rate without changing the liquid class.
Dispense flow rate (0–500 µL/
s)
The numerical value or the JavaScript variable
that will override the dispense velocity setting in
the liquid class.
A JavaScript variable enables the value to be
assigned later, for example through a VWorks
form. Using a VWorks form, an operator could
easily change the flow rate for a dispense step in
increments from as low as 1 µL/min up to
1001 µL/min using the same liquid class.
If the task is included in a VWorks macro, a
JavaScript variable enables you to change the
value for the task at the macro level.
IMPORTANT The software requires that the
flow rate value be in microliters per second (µL/s)
at run time. If you want an operator to enter the
value in microliters per minute (µL/min), you can
use scripting to convert the values for the
software to use.
Distance from well bottom
(mm)
The absolute distance between the end of the
pipette tips and the bottom of the Tip Wash
Station during the Dispense to Waste task.
If you specify dynamic tip retraction, this is the
starting distance.
IMPORTANT The labware definition must be
accurate and the teachpoint must be precise in
order for the system to position the tips at the
correct distance from the well bottom.
