Watson Marlow 120S/DV Peristaltic Pump

• Precise dosing and metering in laboratory settings.
• Fluid transfer in cleanroom and sterile environments.
• Handling sensitive biological fluids and reagents.
• Chemical addition in small-scale process applications.
• Sampling and analytical procedures requiring controlled flow.

Typical flow rate range

For this class of equipment, flow rates commonly range from microlitres to several hundred millilitres per minute.

Motor speed range

Units of this type typically offer a motor speed range from less than 1 rpm up to 200 rpm or more, allowing for fine control.

Tubing compatibility

Peristaltic pumps like the 120S/DV commonly accept tubing with a 1.6mm wall thickness, accommodating various internal diameters.

Control options

Typically, these pumps feature both manual and remote control options, often including analogue inputs such as 4-20mA or 0-10V.

Typical footprint

Peristaltic pumps in this category are generally compact and designed for benchtop use or integration into cabinets.

Power supply

Units commonly operate on standard single-phase laboratory power supplies, typically 100-240V AC.

Maintenance requirements

Peristaltic pumps are known for their low maintenance, primarily requiring periodic tube replacement.

• What types of fluids can a peristaltic pump handle?

  Peristaltic pumps can handle a wide range of fluids, including corrosive chemicals, viscous liquids, and shear-sensitive biological solutions, as the fluid only contacts the tubing.

• Is this pump suitable for continuous operation?

• How accurate is the dosing with a peristaltic pump?

• What is the typical lifespan of the tubing?

• Can this pump be used in a sterile environment?

• What is the maximum pressure a peristaltic pump can generate?

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.
