LAA-02 Laboratory Dual Syringe Pump

The LAA-02 dual-channel syringe pump is designed to hold two syringes, plastic or glass, ranging from 10 μL to 60 mL. It provides a wide flow range of 0.184 nL/min to 83.318 mL/min and supports multiple working modes for precise infusion and withdrawal operations. The 4.3" color LCD touchscreen enables intuitive parameter configuration, real-time monitoring, and easy syringe selection from various manufacturers and specifications. With its high-precision control, the pump ensures stable and reliable fluid delivery in laboratory and industrial applications.

Equipped with RS485 communication supporting the MODBUS protocol, the LAA-02 allows remote control and synchronization with external systems. Its full metal housing ensures durability and stable performance under demanding conditions, while protective features and alarm systems safeguard operation and equipment.
