The 15-Channel Microfluidic Pressure Pump (Basic) provides precise pneumatic flow control for microfluidic applications requiring multiple independent pressure lines. This compact system delivers pressures from 0 to 0.7 MPa across 15 separate channels with 0.001 MPa accuracy, enabling researchers to control complex multi-inlet microfluidic devices with consistent, stable flow rates.
The system combines manual button operation with PC software control, allowing both standalone operation and computer-integrated workflows. The pressure-driven flow mechanism eliminates pulsation associated with syringe pumps while providing the channel capacity needed for sophisticated microfluidic experiments involving multiple reagents, samples, or culture media streams.
How It Works
The system operates on pneumatic pressure control principles, where compressed air or inert gas is regulated through precision pressure controllers for each of the 15 channels. Unlike peristaltic or syringe pumps that generate pulsatile flow, pneumatic pressure creates steady, continuous flow through microfluidic channels when combined with appropriate flow resistances.
Each channel maintains independent pressure control through dedicated regulators that respond to manual button inputs or software commands via the PC interface. The 0.001 MPa accuracy ensures precise flow rate control when combined with known channel resistances, following the relationship Q = ΔP/R where flow rate equals pressure difference divided by fluidic resistance. The 0.7 MPa maximum pressure provides sufficient driving force for most microfluidic applications while remaining compatible with standard PDMS and glass devices.

Practical Tips
Verify pressure accuracy monthly using a calibrated reference gauge connected to unused channels.
Why: Pressure drift can affect flow reproducibility in quantitative experiments.
Install inline filters in the main air supply line and replace them when pressure regulation becomes sluggish.
Why: Contaminated air supply can damage internal regulators and affect pressure stability.
Characterize pressure-flow relationships for each microfluidic device configuration before critical experiments.
Why: Channel geometry variations affect flow resistance and optimal pressure settings.
If channels show pressure cross-talk, check for leaks in tubing connections and ensure proper channel isolation.
Why: Pressure leaks can cause unintended flow interactions between supposedly independent channels.
Allow 5-10 minutes for pressure stabilization after major pressure changes before collecting data.
Why: Pneumatic systems require equilibration time for optimal flow stability.
Never exceed the 0.7 MPa maximum pressure limit as this may damage microfluidic devices or create safety hazards.
Why: Overpressure can cause catastrophic device failure and potential injury from high-velocity fluid ejection.
Use dedicated channels for each fluid type to prevent cross-contamination between experiments.
Why: Residual fluids in pressure lines can contaminate subsequent experiments if channels are shared.
If software control becomes unresponsive, verify USB connection and restart both software and hardware controllers.
Why: Communication errors can cause control lag or channel misbehavior during automated protocols.

Compliance
What flow rate range can this system achieve with typical microfluidic devices?
Flow rates depend on your specific microfluidic channel geometry and fluid viscosity. With standard 100 µm wide channels, expect flow rates from 10 nL/min to 100 µL/min. The 0.001 MPa pressure resolution enables fine flow control for applications requiring stable nanoliter-scale flows.
How do I determine the correct pressure setting for my desired flow rate?
Flow rate follows Q = ΔP/R where Q is flow rate, ΔP is pressure difference, and R is channel resistance. Measure your device's flow resistance experimentally by applying known pressures and measuring resulting flow rates, then use this calibration curve for subsequent experiments.
Can this system handle viscous solutions or cell suspensions?
Yes, the pneumatic pressure approach works well with viscous solutions up to the 0.7 MPa maximum pressure limit. For cell suspensions, ensure your microfluidic channels are appropriately sized (typically >50 µm) to prevent clogging and maintain cell viability.
What is the pressure stability over time for long-term perfusion experiments?
Consult the product datasheet for specific stability specifications. Pneumatic systems typically provide better long-term stability than syringe pumps since they eliminate mechanical drift, but performance depends on your air supply quality and temperature stability.
How does software control integrate with other laboratory automation systems?
The PC software provides programmatic control for automated protocols. Check the software documentation for available APIs or communication protocols if integration with existing laboratory management systems is required.
What maintenance is required for reliable operation?
Regular maintenance includes checking pressure line connections, replacing inlet filters, and periodic pressure calibration verification. The pneumatic design requires minimal mechanical maintenance compared to pump-based systems.
