Watson Marlow 120S/DV Peristaltic Pump

• Laboratory dosing and dispensing of sensitive fluids.
• Chemical addition in small-scale processes.
• Bioreactor feeding and sampling.
• Analytical instrument fluid delivery.

Typical flow rate

Units in this series typically offer low flow rates, often ranging from microlitres to tens of millilitres per minute, suitable for precision applications.

Pumphead type

This model commonly features a 120S pumphead, designed for single-channel fluid transfer.

Control type

The 'DV' designation often indicates a drive with variable speed control, typically via a front panel or remote input.

Tubing size compatibility

For this class of pump, tubing with internal diameters typically ranging from 0.5 mm to 4.8 mm is used, depending on the specific pumphead configuration.

Power supply

Commonly operates on a standard single-phase electrical supply, typically 100-240V AC, 50/60 Hz.

Footprint

Known for its compact design, making it suitable for benchtop use in laboratories or integrated systems.

• What kind of fluids can this pump handle?

  Peristaltic pumps are suitable for a wide range of fluids, including corrosive, abrasive, viscous, and shear-sensitive liquids, as the fluid only contacts the tubing.

• Is this unit suitable for continuous operation?

• What maintenance is typically required for this pump?

• Can this pump be used for sterile applications?

• What is the typical lifespan of the tubing?

Peristaltic pumps are valued in laboratory and pharmaceutical settings for their gentle, non-contact fluid handling, making them suitable for delicate samples and sterile applications. When buying used units, buyers typically prioritise checking tubing condition, motor functionality, and calibration history. Industry sentiment favours these pumps for their reliability, low maintenance requirements, and consistent flow rates. Common strengths include versatility across various fluid viscosities and compatibility with corrosive or shear-sensitive media. Prospective buyers should verify spare parts availability for specific models.
