Cole-Parmer Masterflex L/S Digital Precision Peristaltic Pump Drive 7528-30

The Cole-Parmer Masterflex L/S Digital Precision Peristaltic Pump Drive, model 7528-30, is a versatile and reliable variable-speed drive designed for precise fluid transfer in laboratory, industrial, and process applications. This unit features a digital interface with an intuitive LCD display for easy control of speed, direction, and calibration, supporting flow rates dependent on compatible pump heads and tubing (typically up to 1700 mL/min with appropriate configurations). It operates at speeds from 1 to 100 rpm, making it ideal for metering, dispensing, and sampling tasks in pharmaceuticals, biotechnology, water treatment, and chemical processing. Key benefits include maintenance-free brushless motor technology for long life, reversible flow for flexibility, and IP33-rated enclosure for protection against dust and splashes. Compared to similar products like Watson-Marlow or other Masterflex models, it offers superior digital precision and universal voltage compatibility (90-260 VAC), reducing setup complexity and enhancing portability. Drawbacks may include the need for separate pump heads and tubing (not included), which adds to initial costs, and a maximum speed limit that may not suit high-flow demands without upgrades. Overall, its compact design, ease of use, and accuracy make it a preferred choice for controlled fluid handling, with the unit appearing new in original packaging based on provided images, including manual and certifications.
