Dispensing peristaltic pump GD200-1B has LCD displaying run parameters and running status. The pump could run continuously at desired flow rate and speed, and also could complete the dispensing function. The flow rate calibration and dispensing calibration ensure the high accuracy and precision. With DC brushless motor, the pump could drive up to 3 single-channel pump heads and offers flow rate from 0.7 mL/min to 2000 mL/min per channel. And the dispensing volume is from 0.1 mL to 99.9 L.
Main Functions and Features
Three Color-Coded Work Modes – The intuitive display features three distinct color-coded operating modes: Continuous Mode, Time Mode, and Volume (Dispensing) Mode, allowing users to quickly identify the current operating status.
Touchscreen + Physical Button Control – Combines a responsive touchscreen with physical control buttons for simple, smooth, and reliable operation, providing flexibility for different working environments.
Closed-Loop Constant-Flow Control – An integrated flow meter and closed-loop control algorithm continuously monitors and adjusts pump operation to maintain stable and accurate constant-flow delivery.
Voice Control – Supports hands-free voice operation, allowing convenient, contactless control when the operator's hands are occupied or when minimizing physical contact is preferred.
Low-Noise Operation – Engineered for quiet operation to provide a comfortable laboratory working environment and minimize disturbance during extended experiments.
Three-Level User Access & Data Logging – Provides three levels of user access control along with exportable operation logs, supporting data traceability, quality management, audits, and compliance requirements.
