Pump
Module.
Automates liquid aspiration and dispensing workflows that require continuous flow, high volumes, or fluid types beyond the range of air displacement pipetting. The Dorna TA carries a needle end effector to any vessel on the fixture plate while a fixed pump handles the fluid movement. Pump-agnostic — syringe, peristaltic, diaphragm, and more.
One Architecture, Any Pump
The system supports any pump type — choose based on your application, not our hardware.
Syringe Pump
Precise, low-volume dispensing with high repeatability. Ideal for small, accurate aliquots and serial dilutions.
Peristaltic Pump
Continuous flow with gentle handling. Best for shear-sensitive biological fluids, media, and buffers.
Diaphragm Pump
Chemical resistance for aggressive solvents and reagents. Handles fluids that destroy other pump types.
Robot-Carried Needle
The needle mounts directly on the Dorna TA as an end effector. The robot moves it with full 6-axis precision to any position on the fixture plate — between tubes, vials, bottles, plates, and reservoirs. The needle is application-specific: length, diameter, and material are selected based on vessel geometry, fluid type, and chemical compatibility. A short, wide-bore needle for high-viscosity fluids. A long, fine needle for deep tube access. A chemically resistant needle for aggressive solvents. The needle is replaceable — swapping for a different application is straightforward without modifying the rest of the system.
- Full 6-axis positioning to any vessel
- Application-specific needle selection
- Tool-free needle swap between applications
Pump-Agnostic by Design
The pump sits fixed on or beside the fixture plate — it never moves. Tubing connects the pump outlet to the needle on the robot arm, following the robot's motion through a managed cable and tubing routing system. Because the robot only handles the needle mechanically, the pump type is entirely determined by what the application needs. Syringe pumps for precise, low-volume dispensing. Peristaltic pumps for continuous flow and gentle handling of shear-sensitive fluids. Diaphragm pumps for aggressive chemicals requiring chemical resistance. Existing pumps already in your lab can often be integrated directly.
- Fixed pump, moving needle — clean separation
- Managed tubing routing follows robot motion
- Integrate your existing lab pumps
Beyond Pipetting Range
The Pump Module covers liquid handling tasks that fall outside the range of air displacement pipetting — higher volumes, continuous flow, viscous fluids, or chemically aggressive reagents. Common applications include reagent addition, buffer dispensing, sample dilution, bulk transfers, and filling of tubes, vials, or plates. The same needle that aspirates from one vessel can dispense into multiple destinations in a single workflow cycle — reducing handling steps and increasing throughput.
- High-volume and continuous flow transfers
- Viscous fluids and aggressive solvents
- One aspirate, multiple dispense destinations
Dorna Workspace Integration
Pump operation — flow rates, volumes, aspiration and dispense timing — is configured and controlled through Dorna Workspace. Pump steps chain seamlessly with tube handling, capping, pipetting, inspection, and any other module in the system. No separate pump control software required. The entire workflow, including pump control, runs from a single interface.
- Flow rates, volumes, and timing in one place
- Chain with any other Dorna module
- No separate pump control software
