Watson Marlow 313DW Peristaltic Pump Head

• Accurate, contamination-free chemical dosing in laboratory and industrial settings.
• Transfer of sensitive biological fluids in biotechnology and pharmaceutical research.
• Metering of viscous or shear-sensitive liquids in food and beverage production.
• Dispensing of reagents and media in analytical and diagnostic laboratories.
• Handling corrosive or abrasive slurries in various industrial processes.

Typical flow rate

Up to 2,000 mL/min for this class of pump head, depending on tubing bore and drive speed.

Tubing compatibility

Commonly accepts 1.6 mm wall thickness tubing with bore sizes typically ranging from 0.5 mm to 8 mm.

Roller mechanism

Units of this type typically feature a three-roller mechanism for high flow, with four-roller options available for smoother flow.

Construction materials

Typically includes glass-filled polypropylene, IXEF, glass-filled nylon, and MoS₂-filled nylon for chemical resistance and durability.

Extension capability

This model commonly allows for the addition of multiple extension pump heads, depending on tubing size and drive capability.

Drive compatibility

Designed to integrate with compatible Watson-Marlow 300 series pump drives.

• What is the primary benefit of a peristaltic pump head?

  Peristaltic pump heads offer contamination-free pumping as the fluid only contacts the tubing, making them ideal for sensitive or sterile applications. They are also capable of handling viscous fluids and slurries.

• How easy is it to change tubing on this pump head?

• Can this pump head be used for continuous operation?

• What kind of maintenance does a peristaltic pump head require?

• Is a drive unit included with this pump head?

Pump heads and accessories are valued for their reliability and compatibility with established laboratory and biotech systems. Buyers typically prioritize condition of seals, tubing compatibility, and flow rate specifications when purchasing used units. Common strengths include longevity when properly maintained and availability of replacement parts. Key considerations include verifying previous calibration records, checking for corrosion or wear, and confirming material compatibility with intended fluids. Industry sentiment favours reputable manufacturers known for precision engineering and robust construction.
