The Precision Peristaltic Pump is a dual-channel microfluidic pump designed for continuous flow applications requiring precise fluid delivery across a wide dynamic range. With flow rates spanning 0.0002 to 380 mL/min and speed control from 0.1 to 100 rpm, this pump accommodates both micro-scale and moderate volume flow requirements in laboratory settings.
The peristaltic mechanism utilizes rotating rollers to compress flexible tubing, creating pulse-free flow without direct contact between pump components and sample fluids. This design prevents contamination and enables handling of aggressive chemicals, biological samples, and sterile solutions. The RS-485 interface with external signal capability allows integration into automated systems and remote monitoring applications.
How It Works
Peristaltic pumping operates through positive displacement using rotating rollers or shoes that compress flexible tubing against a curved track. As rollers rotate, they create traveling occlusions that push fluid through the tube in discrete volumes. The pumped fluid never contacts the pump mechanism, remaining isolated within the tubing throughout the process.
Flow rate control is achieved by varying the rotational speed of the roller assembly, with precise speed regulation from 0.1 to 100 rpm. The dual-channel design enables simultaneous operation of two independent fluid streams, each with its own tubing set and flow characteristics. The RS-485 interface provides digital communication for automated control and monitoring integration.

Practical Tips
Verify flow rates using timed collection with graduated vessels at your specific operating conditions.
Why: Tubing properties and system backpressure affect actual flow rates compared to programmed settings.
Replace tubing before visible wear or cracking develops, typically after 100-500 hours of operation.
Why: Worn tubing causes flow rate drift and potential contamination from tube failure.
Prime all tubing thoroughly and eliminate air bubbles before connecting to sensitive downstream equipment.
Why: Air bubbles cause flow pulsations and can interfere with microfluidic device operation.
If flow appears irregular, check tubing installation and roller engagement before adjusting speed settings.
Why: Improper tubing placement is the most common cause of flow inconsistency in peristaltic systems.
Monitor flow consistency by measuring collected volumes over extended periods for critical applications.
Why: Long-term drift can occur due to tubing wear or temperature changes affecting pump performance.
Use appropriate chemical-resistant tubing when handling corrosive or toxic fluids.
Why: Tubing failure with hazardous chemicals poses safety risks and can damage pump components.
Install check valves or flow sensors downstream when precise flow control is critical.
Why: External monitoring provides feedback for automated systems and validates pump performance.

Background reading relevant to this product:
What tubing materials are compatible with this pump?
Standard peristaltic pump tubing including silicone, PVC, Tygon, and chemical-resistant formulations. Tubing selection depends on chemical compatibility requirements and desired flow characteristics.
How accurate is the flow rate control across the operating range?
Flow rate accuracy depends on tubing consistency and calibration. Consult product datasheet for specific accuracy specifications at different flow rates and operating conditions.
Can both channels operate at different flow rates simultaneously?
Yes, each channel operates independently with its own speed control, allowing different flow rates and tubing types to be used concurrently.
What is the maximum pressure this pump can generate?
Maximum pressure depends on tubing properties and pump speed. Consult product datasheet for pressure limitations with specific tubing types and operating conditions.
How do I integrate this pump with existing laboratory automation systems?
Use the RS-485 interface for digital communication and external signal inputs for trigger-based operation. Compatible with most laboratory control software supporting RS-485 protocols.
What maintenance is required for long-term operation?
Regular tubing replacement based on usage, periodic cleaning of roller assemblies, and calibration verification. Tubing wear is the primary maintenance consideration in peristaltic systems.
Can this pump handle viscous fluids or solutions with particulates?
Peristaltic pumps can handle moderate viscosity fluids and small particulates. Flow rate and pressure capabilities decrease with increasing fluid viscosity.
