Watson-Marlow 620S/R Peristaltic Pump with Brushless DC Motor and Digital Control
Product Description
The Watson-Marlow 620S/R is a precision industrial peristaltic pump from the 600 Series, engineered for applications in biotechnology, molecular diagnostics, and bioprocessing. Featuring a brushless DC motor and a digital keypad control interface, it delivers exceptional accuracy and reliability critical in biopharmaceutical production pipelines.
- Flow rate ranges from 0.00026 to ~4.76 gallons per minute (0.001–18 L/min) depending on the selected pump head, supporting delicate fluid handling tasks essential in synthetic biology research and molecular cloning workflows.
- The pump exhibits a maximum pressure capacity of approximately 60 psi (4 bar), suitable for a wide range of clinical diagnostics and biomanufacturing processes.
- It offers precise speed control between 0.1 and 265 rpm with a fine turndown ratio of 2,650:1 and 0.1% speed accuracy, facilitating critical dosing accuracy in molecular biology protocols.
The pump supports interchangeable heads:
- 620R Mk II (continuous tubing, two rollers)
- 620RE & 620RE4 LoadSure heads (two or four rollers) with retractable rollers for easy cleaning (CIP/SIP), making it widely adopted in clean bioprocessing environments.
Compatible tubing options include Marprene™, Bioprene™, Sta-Pure™, and silicone, accommodating inner diameters from 6.4 to 17 mm, optimizing versatility for various biotechnological fluid transfer applications.
Constructed with powder-coated die-cast aluminium and a chemically-resistant wipe-down membrane keypad, the enclosure complies with IP31/NEMA 2 standards for dry industrial environments. IP66/NEMA 4X variants are available for more stringent dust and water resistance requirements common in biomedical engineering labs.
Additional features enhancing workflow integration include:
- MemoDose for precise single-shot volumes, critical in gene editing and synthetic biology dosing routines.
- Ramp function and non-drip operation to minimize fluid stress and avoid contamination in sensitive bioprocessing operations.
- Optional RS-232 data export facilitating batch record keeping and GMP compliance in regulated biotechnology manufacturing settings.
The 620S/R’s relatively low noise level (<70 dB(A)) and robust construction make it an excellent choice for continuous use in research laboratories focusing on fluorescence analysis, cell imaging workflows, and live-cell bioprocessing applications.
