The 2-Channel Precision Syringe Pump delivers controlled dual-channel fluid dispensing for microfluidics, droplet generation, and analytical chemistry applications. Two independent syringe channels operate simultaneously, supporting protocols that require accurate flow rates and reproducible delivery volumes across extended experimental runs.
The pump accepts syringes from 50 µl to 200 ml, with micro-step resolution of 0.107 µl (using a 10 ml syringe). Linear speed range spans 1–65 mm/min with over 30 kgf of thrust, providing reliable displacement even with viscous fluids. A 3.2-inch LCD touchscreen interface allows direct parameter entry — syringe model selection from a built-in list or manual ID input, flow rate configuration across six units (µl/s, µl/min, µl/hr, ml/s, ml/min, ml/hr), and target volume setting with automatic stop.
The system supports both infusion and withdrawal modes, with power-interruption recovery that restores previous parameters on restart. Operates on DC 24V power in environments from 5–40°C.
How It Works
The precision syringe pump operates through controlled mechanical displacement of syringe plungers driven by stepper motor assemblies. Each channel contains an independent drive mechanism that advances the syringe plunger at programmed rates, creating positive displacement flow with minimal pulsation.
Flow rate accuracy depends on the precise mechanical displacement of the syringe volume combined with the temporal control of the drive mechanism. The system maintains consistent delivery by eliminating pressure-dependent flow variations common in peristaltic systems, instead relying on direct volumetric displacement.
Dual-channel operation allows simultaneous control of two fluid streams with independent flow rates, enabling mixing ratios, droplet generation, and multi-inlet experimental configurations. Each channel operates independently while sharing common control electronics and user interface.

Practical Tips
Verify flow rates gravimetrically using analytical balances for each channel before critical experiments.
Why: Ensures accurate delivery volumes for quantitative analytical procedures.
Clean syringe assemblies with appropriate solvents after each use to prevent contamination.
Why: Maintains dispensing accuracy and prevents cross-contamination between experiments.
Prime both channels thoroughly to eliminate air bubbles before starting experiments.
Why: Air bubbles can cause flow irregularities and affect droplet generation consistency.
Use appropriate syringe sizes for your required flow rate range and total volume needs.
Why: Proper syringe selection optimizes flow accuracy and experimental duration.
Check for leaks at all connection points if flow rates become inconsistent.
Why: Loose connections reduce system pressure and compromise volumetric accuracy.
Monitor and record environmental temperature as it can affect fluid viscosity and flow characteristics.
Why: Temperature variations impact fluid properties and can introduce systematic errors in delivery volumes.
