The Precision Syringe Pump, Dual Channel is a high-accuracy laboratory fluid delivery system engineered for applications requiring simultaneous, independent control of two syringe channels. Designed for research environments where consistent flow rates and precise volume delivery are critical, this dual-channel configuration enables parallel infusion, withdrawal, or push-pull operations without cross-channel interference.
The pump accommodates a wide range of syringe sizes and delivers ultra-low to high flow rates with minimal pulsation, making it well-suited for microfluidics, drug discovery, pharmacology, and chemical synthesis workflows. The intuitive interface allows users to set flow rates, target volumes, and operational modes independently for each channel.
Key Features
- Dual independent channels for simultaneous infusion/withdrawal
- Wide flow rate range with high precision and low pulsation
- Compatible with standard laboratory syringes across multiple sizes
- Multiple operational modes: infusion, withdrawal, and push-pull
- Digital display with intuitive parameter input
- Compact benchtop design suitable for sterile and standard lab environments
Applications
- Microfluidic chip perfusion and droplet generation
- Drug delivery and pharmacokinetic studies
- Chemical synthesis and reaction control
- Cell culture media perfusion
- Calibration and fluid metering tasks
How It Works
The Precision Syringe Pump, Dual Channel uses two independent stepper motor-driven lead screws to advance or retract syringe plungers at precisely controlled rates. Each channel is governed by its own motor controller, allowing completely independent flow parameters — rate, direction, and target volume — to be set and executed simultaneously.
The digital control system translates user-entered flow rate and syringe diameter values into precise motor step sequences, delivering smooth, low-pulsation flow. An optical encoder on each axis provides real-time position feedback, compensating for any backlash and maintaining accuracy across the full range of supported flow rates.
Features & Benefits
- Dual Independent Channels — Two fully independent drive systems operate simultaneously without cross-channel interference, enabling infusion/withdrawal, push-pull, or two-fluid mixing configurations
- Wide Flow Rate Range — Covers nanoliter to milliliter per minute ranges with high linearity and minimal pulsation across syringe sizes
- Universal Syringe Compatibility — Accepts standard glass and plastic syringes from 1 µL to 60 mL; interchangeable holders simplify syringe changes
- Multi-Mode Operation — Infuse, withdraw, or push-pull per channel; target-volume auto-stop prevents over-delivery

Practical Tips
- Always zero the pump position and load a fresh syringe before starting a new protocol to avoid residual volume errors
- For viscous fluids, reduce maximum flow rate by 10–20% to prevent stall and maintain accuracy
- Use glass syringes for organic solvents or aggressive reagents; check syringe compatibility before use
- When running push-pull mode, balance syringe sizes and rates carefully to maintain zero net pressure on the connected chamber
- Prime tubing thoroughly before connecting to sensitive preparations — even small air bubbles can disrupt microfluidic chip performance
Setup Guide
- Mount the desired syringes into the appropriate channel holders and secure the plunger clamps
- Power on the pump and use the keypad to select syringe brand and size for each channel independently
- Enter the desired flow rate and target volume for each channel
- Connect tubing to syringe tips and prime the lines to remove air bubbles before connecting to your experiment
- Press RUN to start simultaneous operation; each channel can be paused, stopped, or adjusted independently mid-run
- For automated workflows, connect via RS-232/USB and use the provided command set to program multi-step protocols

Compliance
Manufactured under ISO 9001 quality management standards. Designed for laboratory research use. Not intended for clinical, diagnostic, or in vivo use without additional validation.
- Can both channels run at different flow rates simultaneously?
- Yes. Each channel is driven by an independent stepper motor and controller, so flow rate, direction, and target volume are fully independent and can differ between channels during the same run.
- What syringe sizes are compatible?
- The pump accepts standard 1 µL to 60 mL syringes from major manufacturers. Interchangeable syringe holders are included for common sizes; custom holders are available for non-standard formats.
- Is RS-232/USB control included?
- Yes. The pump includes a serial port and USB interface with a published command set for remote control and data logging from a PC or automation system.
- Can the pump be used with organic solvents?
- Glass syringes are recommended for aggressive solvents. Wetted parts in the fluid path are limited to the syringe barrel and tip — verify syringe material compatibility with your specific reagents before use.
