Watson Marlow 323 Peristaltic Pump

• Precision dosing and dispensing in laboratory settings.
• Transfer of shear-sensitive fluids in biotechnology.
• Chemical addition and sampling in light industrial processes.
• Sterile fluid transfer in pharmaceutical research and development.

Typical flow rate range

Typically ranges from microlitres per minute up to several litres per minute, depending on the pumphead and tubing fitted.

Power supply

Commonly operates on standard single-phase mains power, typically 100-240V AC, 50/60Hz.

Control interface

Often features a membrane keypad and digital LCD for speed control, with some models offering analogue inputs/outputs or RS-232 for remote control.

Ingress Protection (IP) rating

Units of this type commonly have an IP31 rating, indicating protection against solid objects over 2.5mm and vertically falling drops of water.

Tubing compatibility

Designed for use with various tubing materials (e.g., Marprene, Bioprene, Silicone) to suit different chemical compatibilities and application requirements.

Footprint

Typically a compact benchtop unit, suitable for laboratory environments where space may be limited.

• What are the main advantages of a peristaltic pump?

  Peristaltic pumps offer contamination-free pumping as the fluid only contacts the tubing. They are also gentle on shear-sensitive fluids and provide precise, repeatable flow rates.

• Can this pump handle corrosive chemicals?

• Is this unit suitable for continuous operation?

• What maintenance is typically required for a peristaltic pump?

• How do I control the flow rate on this pump?

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.
