Watson Marlow 313DW Peristaltic Pump Head - Watson Marlow SCIQ 323 Peristaltic Pump

• Precise dosing and dispensing in laboratory settings.
• Transfer of sensitive biological fluids and cell cultures.
• Chemical reagent addition in analytical processes.
• Sterile fluid transfer in pharmaceutical research and development.

Typical flow rate range

For this class of equipment, flow rates commonly range from microlitres to several litres per minute, with units like the SCIQ 323 typically offering up to 2000 ml/min.

Speed control

Units of this type commonly feature variable speed control, often in 1 rpm steps, providing precise flow adjustment.

Number of channels

While a single pump head is standard, models like the SCIQ 323 can typically be extended to support multiple channels (e.g., up to five or ten with specific heads).

Tubing compatibility

Peristaltic pumps are designed for various tubing wall thicknesses and materials, allowing for different pressure and fluid compatibility requirements.

Power supply

Units in this category are commonly switchable between 100-120V and 220-240V to suit different regional power standards.

Footprint

Benchtop peristaltic pumps typically have a compact footprint, suitable for laboratory environments.

• 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 flow control.

• Can this pump handle corrosive chemicals?

• Is this unit suitable for continuous operation?

• What maintenance is typically required for a peristaltic pump?

• How accurate is the dosing with a peristaltic 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.
