The 6+2 Channel Constant Pressure Pump System is a precision microfluidic pressure controller designed for automated flow control in lab-on-chip applications, droplet generation systems, and perfusion experiments. This system delivers constant pressure across 8 independent channels (6 positive pressure, 2 negative pressure) with precise control from 10 kPa to 0.4 MPa positive pressure and -100 to -1 kPa negative pressure ranges.
The system features a 7-inch touchscreen interface for intuitive operation and real-time pressure monitoring. Its dual-mode capability enables complex microfluidic workflows including cell perfusion, droplet formation, and multi-stream mixing applications. The compact benchtop design integrates seamlessly into existing laboratory setups while providing research-grade precision for demanding microfluidic experiments.
How It Works
The system operates on pneumatic pressure control principles, using precision pressure regulators to maintain constant pressure across multiple independent channels. Positive pressure channels (10 kPa to 0.4 MPa range) drive fluid flow by applying controlled air pressure to sealed fluid reservoirs, while negative pressure channels (-100 to -1 kPa) create suction for waste removal or valve actuation.
The pressure control mechanism employs feedback loops to maintain stable pressures regardless of downstream resistance changes. The 7-inch touchscreen interface displays real-time pressure readings and allows independent adjustment of each channel. This approach enables precise flow control in microfluidic devices where flow rates are determined by the pressure differential across microchannels with known hydraulic resistance.
The dual positive/negative pressure capability allows complex fluidic operations including active mixing, droplet sorting, and multi-phase flow control within a single integrated system.

This system combines multi-channel capability with dual positive/negative pressure control and intuitive touchscreen operation. The wide pressure range and independent channel control provide versatility for diverse microfluidic applications from cell perfusion to droplet generation.
Practical Tips
Verify pressure readings against a calibrated reference gauge monthly to ensure measurement accuracy.
Why: Pressure sensor drift over time can affect flow rate reproducibility in microfluidic experiments.
Inspect pneumatic connections weekly for leaks using soapy water solution at fitting joints.
Why: Pressure leaks can cause unstable flow rates and reduce system performance.
Start with minimum required pressure and gradually increase to avoid damaging delicate microfluidic devices.
Why: High initial pressures can cause channel deformation or bonding failure in PDMS-based devices.
If pressure cannot be achieved, check for air bubbles in fluid lines and ensure reservoir caps are properly sealed.
Why: Air leaks in the system prevent effective pressure transmission to the microfluidic device.
Allow system to stabilize for 2-3 minutes after pressure changes before starting critical measurements.
Why: Pressure equilibration time ensures stable flow conditions for reproducible experimental results.
Use appropriate pressure ratings for all tubing and fittings, especially when operating near maximum pressure limits.
Why: Component failure under pressure can cause dangerous tube disconnections and equipment damage.
Maintain a log of pressure settings and flow rates achieved for different microfluidic devices.
Why: Documentation enables rapid setup reproduction and troubleshooting of flow rate variations.
Clean touchscreen with isopropyl alcohol and lint-free cloth to maintain display clarity and touch responsiveness.
Why: Laboratory contamination on the screen can interfere with accurate pressure adjustments during experiments.

Can the system interface with external control software?
The system features a touchscreen interface for manual control. Consult product datasheet for details on external software compatibility and communication protocols.
What tubing and fitting compatibility does the system support?
The system accommodates standard pneumatic tubing connections. Specific fitting specifications and compatible tubing materials should be verified in the product documentation.
How quickly can pressures be switched between channels?
Response time depends on system volume and pressure differentials. Consult technical specifications for switching speed and settling time characteristics.
What maintenance procedures are required?
Regular maintenance includes pressure calibration verification and pneumatic line inspection. Detailed maintenance schedules and procedures are provided in the user manual.
Is the system compatible with corrosive or biological fluids?
The system provides pneumatic pressure control, with fluids contained in user-supplied reservoirs. Chemical compatibility depends on reservoir and tubing materials selected by the user.
