Peristaltic Pump Tubing

In a peristaltic pump, the flow rate is determined by both the size of the tubing and the pump speed. Larger tubing produces faster flow rates. You can use the chart below to select the appropriate tubing for the flow rate you need.

In a peristaltic pump, the tubing is the only material that is in contact with the working fluid. This provides a peristaltic pump with certain advantages over other pump types. The first is that you can change the tubing to prevent contamination; since the tubing is all that is wetted, removing it would remove any trace of the previous solvent. The second is that you can tailor the chemical compatibility of the pump to your application; you can use more expensive fluoroelastomer tubing when pumping halogenated solvents and less expensive vinyl or silicone tubing when pumping aqueous solutions.

Silicone Tubing is the most commonly used peristaltic pump tubing. It has the longest service life and good chemical compatibility for aqueous and many organic solvents. Its typical service life is about 150 hrs at 600 rpm and 825 hr at 100 rpm. It can usually be left running on experiments during weekends without much danger of rupture, but a fresh section of tubing should be pulled through the pump rollers before any running peristaltic pump is left unattended. Silicone tubing can also be autoclaved a single time with a wet cycle without a significant reduction in its life.

Vinyl Tubing has the lowest per-foot cost of any peristaltic pump tubing. It has only fair compatibility for many aqueous solvents and does not have any tolerance for most organic solvents. It only has a third of the service life of silicone tubing, about 50 hr at 600 rpm and about 275 hr at 100 rpm. We do not recommend using vinyl tubing in an unattended peristaltic pump. If it must be use in an unattended pump, a fresh section of tubing should be pulled through the pump roller immediately prior to leaving. Vinyl tubing cannot be autoclaved and should not be exposed to temperatures above 80°C.

Fluoroelastomer Tubing is both the most chemically inert peristaltic pump tubing and the shortest lived. It can withstand even halogenated solvents for a short time. Its service life is only about 30 hr at 600 rpm and 165 hr at 100 rpm. Because of the short life, we do not recommend that a peristaltic pump using fluoroelastomer tubing be left unattended. If the pump must be left unattended, a fresh section of tubing should be pulled through the pump roller immediately prior to leaving. Like silicone tubing, fluoroelastomer tubing can be autoclaved a single time with a wet cycle without a significant reduction in its life.
