Dual Syringe pump
Precision dual syringe pump system for independent control of two fluid streams in laboratory applications requiring accurate volumetric dispensing and perfusion protocols.
| Automation Level | semi-automated |
| Brand | ConductScience |
The Dual Syringe Pump is a precision fluid delivery instrument designed for controlled dispensing of two independent fluid streams in laboratory and research applications. This benchtop unit enables researchers to simultaneously manage two syringe-based fluid delivery systems with independent flow rate control, making it suitable for applications requiring precise volumetric dispensing, continuous perfusion, or coordinated dual-reagent delivery.
The instrument supports standard laboratory syringes and provides programmable control over flow parameters. Dual syringe configuration allows for complex experimental protocols involving multiple reagents, buffer exchanges, or simultaneous sample and reference fluid delivery. The system is designed to meet the precision requirements of analytical chemistry, cell culture perfusion, microfluidics, and other applications where accurate fluid handling is critical.
How It Works
The dual syringe pump operates through precise stepper motor-driven linear actuators that control syringe plunger movement at programmable rates. Each syringe assembly is independently controlled, allowing for different flow rates, volumes, and timing sequences between the two fluid channels. The system calculates volumetric flow rates based on syringe diameter and plunger displacement speed, enabling accurate delivery from microliters per minute to milliliters per minute.
Flow rate accuracy is maintained through feedback control systems that monitor motor position and compensate for variations in backpressure or fluid viscosity. The pump can operate in continuous flow mode for perfusion applications or dispensing mode for precise volume delivery. Programming interfaces allow users to create complex protocols involving flow rate changes, start/stop sequences, and coordinated dual-channel operations.

This dual syringe pump combines independent dual-channel control with programmable operation capabilities. The system offers precision fluid delivery suitable for applications requiring coordinated multi-reagent protocols or simultaneous reference and sample fluid management.
Practical Tips
Verify flow rate accuracy periodically using gravimetric measurement with water at room temperature.
Why: Flow rate accuracy can drift over time and varies with fluid properties and temperature.
Clean syringe assemblies with appropriate solvents after each use and store with plungers in mid-position.
Why: Prevents residue buildup and maintains seal integrity for long-term accuracy.
Prime all tubing thoroughly and eliminate air bubbles before starting critical experiments.
Why: Air bubbles cause flow irregularities and can significantly affect volumetric accuracy.
If flow rates are inconsistent, check for blockages in tubing and verify syringe seating in mounts.
Why: Mechanical issues often manifest as flow rate variations before causing complete failure.
Record syringe types, fluid properties, and environmental conditions for each experimental session.
Why: These parameters affect flow characteristics and are essential for reproducing precise protocols.
Use appropriate tubing materials compatible with solvents and ensure proper ventilation for volatile fluids.
Why: Chemical compatibility prevents degradation and safety hazards during extended operations.
