The 10-Channel Constant Flow Microfluidic Pump provides precision flow control across multiple independent channels for advanced microfluidics applications. This research-grade pump system accommodates syringes ranging from 10 μL to 10 mL capacity, delivering flow rates spanning seven orders of magnitude from 0.831 nL/min to 21.675 mL/min per channel. The digital interface combines intuitive knob control with membrane buttons, while RS-485 connectivity enables integration into automated experimental setups.
Each of the ten independent channels maintains constant flow delivery through precision stepper motor control and micro-stepping algorithms. The wide dynamic range supports applications from single-cell perfusion requiring nanoliter flow rates to tissue-scale organ-on-chip systems demanding milliliter volumes. The compact benchtop design (280 × 330 × 140 mm) accommodates standard laboratory space constraints while providing the multi-channel capacity required for complex experimental protocols.
How It Works
The pump operates through precision stepper motor-driven lead screws that advance syringe plungers at controlled rates to maintain constant volumetric flow. Each channel incorporates micro-stepping control algorithms that divide full motor steps into smaller increments, enabling smooth flow delivery without pulsation artifacts. The system calculates flow rates based on syringe diameter and plunger advancement speed, automatically adjusting motor parameters to maintain the programmed flow rate regardless of back-pressure variations within the operating range.
Digital control circuitry monitors motor position and provides feedback correction to compensate for mechanical variations and ensure flow accuracy. The RS-485 interface enables computer control and integration with automated experimental systems, allowing programmed flow sequences, ramping protocols, and synchronized multi-channel operations. Internal flow calculations account for syringe geometry differences across the 10 μL to 10 mL range, maintaining accuracy across the full dynamic range from nanoliter to milliliter flow rates.

Practical Tips
Verify flow rate accuracy by collecting and measuring dispensed volumes over known time periods, especially after changing syringe sizes.
Why: Ensures accurate flow calculations and compensates for any mechanical variations in syringe mounting.
Clean syringe interfaces and tubing connections regularly with appropriate solvents to prevent buildup of residues.
Why: Maintains smooth plunger movement and prevents contamination that could affect flow accuracy.
Prime all tubing thoroughly before starting experiments by manually advancing syringes to remove air bubbles.
Why: Air bubbles cause flow irregularities and can disrupt sensitive cell culture or analytical protocols.
If flow appears irregular, check for proper syringe diameter settings in the digital interface and verify secure syringe mounting.
Why: Incorrect diameter settings lead to flow calculation errors, while loose mounting causes mechanical inconsistencies.
Document syringe lot numbers and mounting positions when flow accuracy is critical for data traceability.
Why: Minor variations between syringes can affect flow precision in quantitative applications requiring high accuracy.
Use appropriate personal protective equipment when handling hazardous solutions and ensure proper ventilation.
Why: Microfluidic applications often involve chemicals or biological materials requiring standard laboratory safety precautions.
Test RS-485 communication and programming sequences before beginning long-duration automated experiments.
Why: Verifies proper interface functionality and prevents experiment interruption due to communication failures.
Keep a log of flow rate verification results for different syringe sizes to identify any systematic variations.
Why: Establishes baseline performance data and enables early detection of calibration drift or mechanical wear.

Compliance
What is the minimum stable flow rate achievable with small volume syringes?
The minimum flow rate of 0.831 nL/min is achievable with 10 μL syringes, suitable for single-cell perfusion and nanoscale applications. Consult product datasheet for flow stability specifications at minimum rates.
Can the pump handle back-pressure from microfluidic resistance?
The precision stepper motor system maintains constant flow delivery against typical microfluidic back-pressures. Maximum back-pressure rating should be verified in the product datasheet for specific applications.
How precise is the flow rate delivery across the dynamic range?
Flow accuracy depends on syringe size and flow rate settings. The system automatically adjusts calculations based on syringe diameter selection. Consult product datasheet for accuracy specifications at different flow rates.
What programming capabilities are available through RS-485 interface?
The RS-485 interface enables computer control of flow rates, start/stop commands, and status monitoring. Programming protocol documentation and command structure are detailed in the user manual.
Can different syringe sizes be used simultaneously across channels?
Yes, each channel can accommodate different syringe sizes from 10 μL to 10 mL. The system requires individual syringe diameter configuration for each channel to ensure accurate flow calculations.
How does the pump maintain flow consistency over long experimental periods?
Constant flow delivery is maintained through precision stepper motor control with position feedback. Flow rate stability over extended periods depends on syringe volume and should be verified for specific experimental durations.
What maintenance is required for optimal performance?
Regular cleaning of syringe interfaces and tubing connections prevents contamination. Motor mechanisms require minimal maintenance, but periodic calibration verification ensures continued accuracy.
Is the pump compatible with standard microfluidic tubing and fittings?
The pump accepts standard syringe connections and works with common microfluidic tubing systems. Specific fitting compatibility depends on syringe outlet design and tubing connection requirements.
