The primary function of the Daisy Gantry is to act as a liquid handler and dispenser, in conjunction with other Daisy instruments. Falcon tubes, vials, microwell plates, or any other containers can be placed on a rack under the moving head, and filled with multiple reagents rapidly and automatically. The Daisy Gantry is great for automating repetitive dispensing actions, setting up sophisticated reagent mixtures, aliquoting large fluid volumes into numerous smaller vials, preparing petri dishes, and so much more. In all applications, the Daisy Gantry ensures that the liquid is dispensed precisely where it is needed, within 100 um in-plane resolution.
With a quick change of the moving head’s attachment, the Gantry seamlessly transforms from liquid handler to plate handler. In fact, we are working with our Early Adopters to further develop this capability in the context of various applications during our beta launch.
The flexibility of the Daisy Gantry makes it an invaluable asset and a workhorse for R&D and commercial laboratories in life sciences, pharmaceutical research and chemical analysis. Please reach out to our team to inquire and learn in-depth about the Daisy Gantry and its capabilities.

Command Set
Always start your automation scripts with the interface set up. Assuming the Daisy Gantry is the first instrument in the first group:
gantry = self.my_interface.groups[0].inst[0]The next step is to home the gantry:
gantry.home()This command by default waits for the finish of the homing action, during which the gantry carriage goes to its starting position (x = 0, y = 0).
Finally, the run command simply moves the gantry carriage to the desired coordinates:
gantry.run(, , ) For instance, here is how you can move the gantry carriage to the coordinates at x = 100 mm, y = 150 mm:
gantry.run(100.0, 150.0, wait=True)
Application Example: Sequential Droplet Dispensing
The script segment below defines the piston pump interface, homes it, then runs a loop to aspirate 640.0 ul of fluid into the pump, and dispenses 10 ul drops.
g1 = self.my_interface.groups[0]
piston_pump = g1.inst[0] # first instrument in the chain is the Daisy Piston
gantry = g1.inst[1] # second instrument in the chain is Daisy Gantry
# Start by homing the pump and the gantry
piston_pump.home()
gantry.home()
# Then, aspirate 1000 ul
pump_capacity = 1000 # ul
aspiration_volume = 640
pull_volume = min(aspiration_volume, pump_capacity)
piston_pump.run(12000, pull_volume, 0, True)
# Determine target positions for the gantry carriage
X_Pos = [50, 60, 70, 80, 90, 100, 110, 120]
Y_Pos = [100, 110, 120, 130, 140, 150, 160, 170]
# Then, dispense in 10 ul increments
dispense_increment = 10
target_volume_location = pull_volume
for X in X_Pos:
for Y in Y_Pos:
gantry.run(X, Y, wait=True)
target_volume_location -= dispense_increment
piston_pump.run(12000, target_volume_location, 1, True)
Daisy Gantry: Automated XY positioning.
Key applications
- Liquid handling
- Aliquoting
- Reagent mixing
- High-volume dispensing
Works with other Daisy modules
Pair the Gantry with a Daisy peristaltic pump such as the Peri T or Peri P, or with the Daisy Piston, for a compact liquid handler. Add a Rotary Valve, Sol Val or Sol Val XL for multi-reagent dispensing.
Click or script
Control the Daisy Gantry with a click in the Daisy Controller Software, or drop into the built-in Python window to automate multi-step protocols. You can control:
- X position (mm)
- Y position (mm)

Frequently asked questions
What labware does the Gantry work with?
Falcon tubes, vials, 96-well and other microwell plates, conical tubes, or any other containers that sit on a rack under the moving head.
How precise is the Gantry?
Liquid is placed within 100 µm in-plane resolution.
Can the Gantry move in Z?
The Gantry is an XY stage. The Daisy Z Stage adds precise Z-axis motion for full 3-axis positioning.
