GD650-1B Intelligent Dispensing Peristaltic Pump is a high-precision fluid dispensing system designed for laboratory automation, chemical dosing, bioprocessing, and industrial fluid handling applications. Featuring a 5-inch touchscreen, programmable dispensing modes, RS485 communication, and advanced flow calibration capabilities, the pump delivers accurate and repeatable fluid transfer with flow rates up to 3250 mL/min.
For applications requiring long-term continuous operation, the GD650-1B can be paired with an optional flow meter to enable closed-loop automatic flow calibration in continuous dispensing mode. This feature continuously compensates for tubing wear and flow variations, helping maintain accurate flow delivery over extended operating periods. The flow meter kit is available separately.
Advanced automation features, including recipe programming, dispensing records, external control interfaces, and optional closed-loop flow control, make the GD650-1B an ideal solution for both research and production environments.
