Spectra/Chrom Tubing Cutter

The Spectra/Chrom Tubing Cutter cuts most polymer tubing, leaving a flat, even edge. The special "V" shape of the tubing holder keeps the tubing perpendicular to the blade. The blade remains sharp for many cuts, but it can easily be replaced.

The Spectra/Chrom Tubing Cutter can be used on most flexible tubing 1/2" (13 mm) OD or smaller. It is not for use on metallic tubing. Use part number 123367 for the tubing cutter and 123368 for a package of 5 replacement blades.



Silicone Tubing (LPS). This is the most commonly used material for peristaltic pump tubing. It provides the longest service life and good chemical compatibility for aqueous and many organic solvents. Its 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. 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 on a wet cycle without a significant reduction in its life.

Vinyl Tubing (LPV). Vinyl tubing has the lowest per-foot cost of any peristaltic pump tubing. It generally has only fair compatibility for many aqueous solvents and does not have a tolerance for many organic solvents. It only has a third of the service life of silicone tubing, 50 hr at 600 rpm and 275 hr at 100 rpm. We do not recommend leaving a peristaltic pump using vinyl tubing unattended. If it must be left unattended, 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 80C.

Fluoroelastomer Tubing (LPF). Flouroelastomer 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 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 flouroelastomer tubing be left unattended. If it must be left unattended, a fresh section of tubing should be pulled through the pump roller immediately prior to leaving. Like silicone tubing, flouroelastomer tubing can be autoclaved a single time on a wet cycle without a significant reduction in its life.



A peristaltic pump works by squeezing the tubing shut at a point and then moving this point of occlusion to force the fluid to move. This makes the wall thickness an important parameter when selecting pump tubing. If the wall is too thin, the pump will not squeeze the tubing completely shut and will not pump at all. If the wall is too thick, the pump will squeeze to hard, reducing the life of the tubing as well as the life of the pump.

The wall thickness of Spectra/Chrom® peristaltic pump tubing is carefully controlled to provide both long tubing life and maximum pumping efficiency.
