Watson Marlow - 323 Peristaltic Pump

Applications & Use Cases

• Precise dosing and metering of sensitive fluids in laboratory settings.
• Transfer of sterile or corrosive liquids in pharmaceutical and biotech research.
• Controlled fluid addition in chemical processing and analytical applications.
• Low-shear pumping of cell cultures and other delicate biological solutions.
• Sampling and dispensing in quality control and R&D laboratories.

Typical Specifications

Typical flow rate range

For this class of equipment, flow rates commonly range from microlitres per minute up to several litres per minute, depending on the tubing size and drive speed.

Power supply

Units of this type typically operate on standard single-phase mains electricity, commonly 230V, 50Hz in the UK.

Control interface

Peristaltic pumps like the 323 often feature digital displays and keypads for setting flow rates, direction, and dispensing volumes. External control options (e.g., analogue, digital I/O) are commonly found.

Tubing compatibility

These pumps are designed to accommodate various tubing materials (e.g., silicone, Marprene, Bioprene) and bore sizes, which dictates flow rate and chemical compatibility.

Pump head type

The 323 model typically uses a multi-roller pump head to ensure smooth, pulsation-reduced flow and extended tubing life.

Footprint

Laboratory peristaltic pumps are generally compact benchtop units, designed to fit within standard lab environments.

Frequently Asked Questions

• What are the main advantages of a peristaltic pump?

  Peristaltic pumps offer contamination-free pumping as the fluid only contacts the tubing. They provide precise flow control, are self-priming, and can handle abrasive, viscous, or shear-sensitive fluids.

• How do I choose the correct tubing for my application?

• Can this pump be used for continuous operation?

• What maintenance is typically required for a peristaltic pump?

• Is this pump suitable for sterile applications?
