Product Description: Micro-speed Variable Peristaltic Pump with Stepper Motor for Chemical Dosing This micro-speed variable peristaltic pump is a precision fluid transfer device specially designed for scenarios such as laboratory precision metering, chemical micro-dosing, biopharmaceutical fluid transfer, and environmental water sample collection. It is suitable for conveying various liquid media including corrosive, viscous, contamination-prone and particle-containing types.Integrating four core advantages—precision micro-speed adjustment with stable flow rate, stepless speed change for adaptability to multiple working conditions, non-contact transfer for contamination prevention, and quiet operation with a compact and durable design—it addresses the pain points of traditional pumps such as low precision in micro-speed transfer, medium contamination and easy clogging. It serves as a core device for achieving the micro-volume, precise and safe transfer of fluids.
