The Touch Screen Constant Laboratory Syringe Pump delivers precise, microprocessor-controlled fluid delivery for research applications requiring accurate flow rates from nanoliters to milliliters per minute. Available in single-channel (CS-LSP01-1C) and dual-channel (CS-LSP02-1C) configurations, this system accommodates syringes from 10 μL to 60 mL with exceptional precision through a 16-subdivision stepper motor drive system.
The pump achieves micro-step resolution of 0.156 microns per 1/16 step, enabling flow rate control from 0.831 nL/min to 43.349 mL/min (single channel) or 86.67 mL/min (dual channel) using 60 mL syringes. Multiple operating modes including infusion, withdrawal, and continuous operation support diverse experimental protocols in microinjection, perfusion, and automated fluid delivery applications.
How It Works
The syringe pump operates through a microprocessor-controlled 16-subdivision stepper motor connected to a precision screw drive system via synchronous belt transmission. This configuration converts rotational motor movement into linear displacement of the syringe plunger with 0.156 micron resolution per micro-step. The stepper motor control allows precise positioning and velocity control across a wide dynamic range, from 1 step per 30 seconds to 867 steps per second.
Flow rate accuracy depends on the linear relationship between plunger displacement and volume dispensed, determined by the syringe barrel diameter. With a 60 mL BD syringe, each 1/16 micro-step delivers 0.0919 μL, enabling flow rates from sub-nanoliter to milliliter per minute ranges. The microprocessor monitors step position and timing to maintain constant flow rates regardless of back-pressure variations within the pump's >280N linear thrust capacity.
Multiple operating modes are achieved through programmed step sequences: infusion (forward steps), withdrawal (reverse steps), and continuous operation (alternating or simultaneous forward/reverse for dual-channel models). The touch screen interface allows real-time parameter adjustment and monitoring of pump status during operation.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Step Resolution | 0.156 microns per 1/16 step with 16-subdivision stepper motor | Standard stepper motors often provide full-step or half-step resolution | Higher resolution enables smoother flow delivery and more precise volumetric control for sensitive applications |
| Flow Rate Range | 0.831 nL/min to 86.67 mL/min (dual channel with 60 mL syringe) | Entry-level pumps often have narrower flow rate ranges | Wide dynamic range accommodates both microinjection and bulk transfer applications without instrument changes |
| User Interface | Touch screen with real-time parameter display and control | Basic models often use button controls or require computer connection | Intuitive operation reduces setup time and enables real-time adjustments during experiments |
| Channel Configuration | Single or dual independent channels with separate controls | Many pumps offer only single-channel operation | Dual-channel capability enables gradient formation, multi-component delivery, and simultaneous bidirectional flow |
| Linear Thrust | >280N thrust capacity | Lower-cost models may have reduced thrust specifications | High thrust maintains flow accuracy with viscous solutions and high back-pressure conditions |
| Operating Modes | Infusion, withdrawal, infusion-then-withdrawal, withdrawal-then-infusion, continuous | Basic pumps often support only infusion and withdrawal modes | Multiple modes support complex protocols including bidirectional flow and automated sequences |
This syringe pump system combines high-resolution stepper motor control with touch screen operation and flexible channel configurations. The wide flow rate range and multiple operating modes provide versatility for applications from microinjection to bulk fluid transfer, while the >280N thrust capacity ensures reliable performance with challenging solutions.

Practical Tips
Verify flow rate accuracy using the specific syringe model you'll use in experiments, as the 0.0919 μL per step specification applies to 60 mL BD syringes.
Why: Flow rate accuracy depends on precise syringe barrel diameter measurements programmed into the pump.
Inspect syringe seals and plunger condition regularly, replacing when wear or damage is observed.
Why: Worn seals cause flow rate drift and compromise volumetric accuracy over time.
Prime the system thoroughly to remove air bubbles before starting flow rate-critical experiments.
Why: Air bubbles create compressible volume that affects flow accuracy and can cause irregular delivery patterns.
Mount the pump on a vibration-free surface and allow 15-20 minutes for thermal equilibration before precise work.
Why: Mechanical vibration and temperature changes can affect stepper motor precision and flow stability.
If flow appears irregular, check for kinked tubing, clogged filters, or insufficient linear thrust for the back-pressure conditions.
Why: The >280N thrust specification has limits, and excessive back-pressure can cause step skipping or stalling.
Record both programmed and measured flow rates during experiments, especially when changing syringe sizes or solution viscosities.
Why: Documentation of actual versus programmed performance provides traceability for regulatory compliance and method validation.
Use appropriate tubing pressure ratings and secure all connections, especially when working with high thrust settings or viscous solutions.
Why: High linear force can cause sudden tube disconnection or rupture if components are not properly rated and secured.
Perform flow rate verification at multiple points across your experimental range, not just at maximum or minimum settings.
Why: Linearity verification ensures accuracy across the full operating range and identifies potential drive mechanism issues.

Compliance
What is the minimum achievable flow rate and how stable is it over long periods?
The minimum flow rate is 0.831 nL/min using a 60 mL syringe, achieved through the slowest step rate of 1 step per 30 seconds. Flow stability depends on environmental temperature control and syringe seal quality over extended periods.
Can the pump handle viscous solutions or high back-pressure applications?
The >280N linear thrust capacity handles viscous solutions and back-pressure conditions typical in microfluidics and perfusion applications. Consult product datasheet for specific viscosity limits and pressure ratings.
How do I calibrate the pump for different syringe sizes?
Flow rate calibration requires entering the syringe barrel diameter into the pump parameters. Verify accuracy by measuring dispensed volume over time using a precision balance, as the 0.0919 μL per step specification applies specifically to 60 mL BD syringes.
What data logging capabilities does the system provide?
Consult product datasheet for data output specifications and connectivity options. The touch screen interface displays real-time parameters, but external logging capabilities may require additional software or hardware.
Can I run both channels independently on the dual-channel model?
The CS-LSP02-1C supports independent channel operation with separate flow rate and volume settings. Each channel can operate in different modes simultaneously (e.g., one infusing while the other withdraws).
What maintenance is required for long-term accuracy?
Regular calibration verification, syringe seal inspection, and drive mechanism lubrication are essential. The stepper motor system requires minimal maintenance, but accuracy depends on syringe condition and proper mounting alignment.
How does this compare to peristaltic pumps for cell culture perfusion?
Syringe pumps provide more accurate flow rates without pulsation but have limited volume capacity requiring syringe changes. Peristaltic pumps offer continuous operation but with inherent pulsation that may affect sensitive cell culture applications.
