Choosing Tubing for your peristaltic pump

A peristaltic pump is a popular appliance in any laboratory. Here you will find some tips for choosing the correct tubing to use for your application with your Peri-Star Pro peristaltic pump.



Size (ID) of Tubing

In a peristaltic pump, the flow rate is determined by both the size of the tubing and the rotor speed. WPI provides two sizes of silicone tubing:

  • 1/16-inch ID tubing for low flow rate at 0.2-18mL/min.
  • 1/4-inch ID tubing for high flow rate at 3.5-280mL/min.


Types of Tubing

  • Silicone tubing has a long service life and good chemical compatibility for aqueous and many organic solvents.
  • Fluoroelastomer tubing should be used when pumping halogenated solvents.
  • Vinyl tubing is used only with chemically compatible solvents.
