Watson Marlow 620S Cased Peristaltic Pump with Brushless DC Motor and Digital Control
Product Description
The Watson Marlow 620S peristaltic pump is a versatile laboratory and industrial pump designed for precise fluid handling and bioprocessing applications. It belongs to the 600 Series of cased peristaltic pumps featuring a chemically resistant, powder-coated die-cast aluminium enclosure with an easy-to-clean membrane keypad. The brushless DC motor provides fine speed control from 0.1 to 265 rpm with an outstanding 2,650:1 turndown ratio and 0.1% speed accuracy, essential for reproducible dosing and biomanufacturing workflows.
Key technical features include:
- Flow range: 0.00026 to ~4.23 gpm (~0.001 to 16 L/min) using the 620R pump head; up to ~4.76 gpm (0.004–18 L/min) with 620RE LoadSure heads
- Pressure capability: Up to 60 psi (4 bar), suitable for various biotechnology and molecular diagnostics processes
- Pump heads: Interchangeable 620R Mk II (two rollers), 620RE, and 620RE4 (two or four rollers) compatible with tubing materials like Marprene™, Bioprene™, Sta-Pure™, and silicone often used in cell imaging and gene editing workflows
- Advanced dosing: MemoDose one-shot dosing, ramp function, non-drip features optimize handling of delicate fluids in synthetic biology and clinical diagnostics
- Control and connectivity: Digital keypad control with optional RS-232 batch record export for GMP compliance in biopharmaceutical production pipelines
- Enclosure: NEMA 2/IP31 vented, suitable for dry industrial environments; IP66/NEMA 4X variants available for wet or dust-prone labs
- Physical attributes: Weight approx. 19.6–20.1 kg depending on pump head; quiet operation below 70 dB(A) at 1 meter
This pump is widely adopted in biotechnology research, molecular biology laboratories, and bioprocessing facilities requiring accurate and reliable fluid transfer, live-cell imaging applications, and precision dosing. Its compatibility with various tubing and advanced control capabilities make it critical for complex workflows in synthetic biology, molecular cloning, and biopharmaceutical manufacturing.
