• What are the main advantages of a peristaltic pump?

  Peristaltic pumps offer contamination-free pumping as the fluid only contacts the tubing, not the pump mechanism. They are also known for their accuracy, gentle handling of shear-sensitive fluids, and ease of maintenance.

• Can this pump handle viscous fluids?

• How often does the tubing need to be replaced?

• Is this unit suitable for continuous operation?

• What type of control does this pump offer?

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.
