LDA-01 Push-Pull Bidirectional Laboratory Syringe Pump

The LDA-01 push-pull syringe pump is designed for low-flow, high-precision, and continuous liquid transfer. It accommodates syringes ranging from 10 μL to 60 mL, offering a flow range of 0.184 nL/min to 99.06 mL/min. Its high-resolution color touchscreen enables intuitive parameter configuration, easy monitoring of operational status, and precise control over fluid delivery. The pump ensures reliable performance and incorporates comprehensive protective features and alarm functions for enhanced safety. External signals can control the pump’s start/stop operations via the built-in RS485 communication, supporting the MODBUS protocol. Additionally, it can be seamlessly integrated with a solenoid valve control box for continuous transmission.
