Dispense – Select the liquid number (1 or 2) and the desired volume, in uL
(Figure 12). Note: If the liquid (1 or 2) being dispensed has not been
primed into the dispense head, the RapidWash will automatically
perform a priming step prior to the first dispense step in the Wash
Program being run. Subsequently, if only that liquid is dispensed in
that Wash Program, the remaining dispense steps will execute without
another priming action.
Figure 12
Delay – Entered as seconds. During a delay the plate is moved away from the
manifold and the washer will not aspirate or dispense until the delay is
over (Figure 13).

2.3 - Prime
The Prime feature allows you to select the liquid number and the total volume (in
uL) dispensed through the dispense manifold. Priming occurs at the priming
trough. During the prime process the trough will self empty to the waste bottle
(Figure 15).
Volume – This is the total volume that will be primed through the system.
Liquid – This allows you to select the fluid source for the prime
Figure 15

Page 13
2.4 - Auto Prime
Auto Prime performs exactly like the Prime feature but will run automatically at
the user determined interval (Figure 16)
Volume – This is the total volume that will be primed through the system.
Liquid – This allows you to select the fluid source for the prime
Time – This is the interval in seconds; a time of 0 deactivates this feature
Figure 16

Page 14
2.5 - Maintenance Mode
The features in this section are used to clean and maintain the performance of the
dispense and aspirate manifolds (Figure 17).
Figure 17
Cleaning Procedure – This feature is used to flush the dispense manifold, it can
be helpful when attempting to remove debris from the dispense manifold. During
the cleaning procedure wash solution is dispensed out of the dispense manifold
into a user supplied trough and aspirated back though the dispense manifold to
waste.
A user-supplied trough is required for this procedure. It is placed in the plate nest
prior to starting the procedure. Clear lids for SBS pipette tip boxes work well and
allow you to see the cleaning cycle during operation.
If a clean, non-system wash solution is desired, the user-supplied trough can be
filled with the desired solution prior to the wash step. The control parameters are
as follows (Figure 18)
14
Page 15
Figure 18
Plate Height - Operates as described previously
Cycles - The number of times the cleaning process will be performed
Volume - This is the volume dispensed through the system: because the fluid path
could be empty after your first cycle you should pay close attention to
this volume to avoid under or over dispensing into your wash plate
Liquid 1, Liquid 2 - Operates as described previously
Soak Delay - Number of seconds the dispense manifold will soak in the dispensed
liquid
Drain Time - The number of seconds the Dispense manifold will aspirate to waste
Empty Manifold – This feature is used to pull vacuum on the aspirate manifold.
The unit does not move and only turns on the vacuum. This feature is typically
used when cleaning the manifold. The manifold does not need to be mounted
on the unit. On the run screen enter time in seconds and press “Run”.
Empty Trough – This feature is used to pull vacuum on the priming trough. The
unit does not move and only turns on the vacuum to the trough. This feature is
used to clear excess fluid from the trough. On the run screen enter time in
seconds and press “Run”.
Dispense Liquid – This feature is used to dispense liquid from unit. The unit does
not move, does not turn on any vacuum, and only dispenses liquid at the current
location. This feature is used to quickly test dispensing functionality. The net
volume dispensed from the unit is exactly as defined in the step, it is not defined
15
Page 16
by the number of wells (i.e. a volume of 9600 would lead to 9.6 mL dispensed
across a 96 well plate or 100 uL in every well). If run without the manifold
attached, volume dispensed will not match what is defined due to a different flow
rate without the head. On the run screen enter volume in uL and press “Run”.
Manual Move – This feature is used to jog the dispense head (Y Axis) IN or OUT,
jog the plate nest (Z Axis) UP or DOWN, and OPEN/CLOSE the plate gripper on
track-based units. Three settings are available for the distance of each jog
movement: 0.1mm, 1mm or 10mm.

2.6 – Change Settings
This Section allows you to modify all the performance settings of the RapidWash
(Figure 19)
Settings Tab:
Aspirate Shift- This is the distance that the RapidWash will use above and in the
plate wells to begin the aspirate step. +mm is above the top of the Plate and –mm
is aspirate begins in the plate.
Dispense Shift- This is the distance that the RapidWash will use above and in the
plate wells to begin the dispense step. +mm is above the top of the Plate and –mm
is aspirate begins in the plate.
Travel Shift- This is the distance that the RapidWash will travel above the Plate
when the manifold moves between Aspirate, Dispense, and Prime Positions. +mm
is above the plate
Teaching Plate- This is the plate height of the microtiter plate that is used on the
calibration procedures (a standard 96 shallow well SBS Plate is usually between
13.5mm-14.0mm).
Dwell Time- This is the delay time the aspirate head stays in the plate after it stops
at the defined depth location. This setting is set in seconds default is 0.5 seconds.
Prime Volume- This is the amount of fluid in uL the RapidWash primes when the
unit switches it liquid path during a wash program.
Figure 19

Page 19
Figure 21
Aspirate Origin- This is the saved position of the aspirate manifold when the
RapidWash begins to aspirate. This position is calibrated with a 96 well teaching
plate. The position should be taught where each set of tips are centered in each
well of the plate (Figure 22).
Figure 22

Page 20
Dispense Origin- This is the saved position of the dispense manifold when the
RapidWash begins to dispense. This position is calibrated with a 96 well teaching
plate. The position should be taught where each set of tips are centered in each
well of the plate (Figure 23).
Figure 23
Track/Nest Height- This Position should only be modified when the unit is used
with a TrackLink on our Lablinx system. This is the beginning position of the
nest, default is 0. When used with a track the position is taught just below the
bottom the track (Figure 26).

Figure 24
Grip Position- This position is only used when a nest with a gripper is attached to
the RapidWash. This is used for through track-based washing only. This is the
Position at which a plate is gripped by the nest before the washing procedure.
This Position is usually taught +5mm above the track (Figure 25)

Calibration tab:
The validation setting turn on/off various checks that the unit can perform prior to
executing programs and priming. Validation checks occur only on the resources
needed for a particular operation (i.e. If liquid 1 is the only fluid being used, the
unit will not validate liquid 2). It is strongly recommended that the validation
checks are not disabled.
- Check Waste Level: Checks if the sensor on the waste bottle is activated.
This may be deactivated for an in-house vacuum and waste management
system.
- Check Liquid 1 Level: Checks if the sensor on liquid bottle 1 detects fluid.
- Check Liquid 2 Level: Checks if the sensor on liquid bottle 2 detects fluid.
- Check Dispense Pressure: Checks if there is pressure for dispensing. This
may be deactivated for motion testing or demo purposes and will run without
dispensing fluid.
- Min Aspirate Vacuum: Checks if there is vacuum supplied to the unit.
WARNING: Disabling this check can lead to flooding!
