Overview
The W09-02R Independent Syringe Pump delivers exceptional precision and versatility for laboratory fluid handling applications. With a maximum stroke of 105mm and stroke resolution of 0.3125μm, this pump provides ultra-precise dispensing capabilities from picoliter to milliliter volumes. The system supports linear speeds from 5μm/min to 200mm/min, making it suitable for both slow, controlled infusions and rapid dispensing protocols.
Key Features
Advanced microprocessor control ensures outstanding accuracy with control precision ≤±0.35% and repeatability precision ≤0.03% F'S. The pump operates in multiple modes including infusion, withdrawal, infusion-withdrawal, withdrawal-infusion, and continuous operations. RS485 communication interface with Modbus-RTU protocol enables seamless integration into automated laboratory systems. The unit supports up to 32 device addresses and features power-off memory retention for uninterrupted workflow continuity.
Applications
Ideal for microfluidics research, drug discovery, cell culture perfusion, analytical chemistry sample preparation, and automated liquid handling systems. The pump's precise flow control makes it essential for applications requiring accurate reagent delivery, sample dilution, or continuous perfusion in biological assays.
