Ismatec: Tubing Selection Guide

Selecting Your Tubing

To complete your Ismatec pumping system, order two- or three-stop color-coded tubing or nominal tubing. A variety of materials and sizes are available, as well as extension tubing.

Tubing Types

2-Stop Tubbing

Two-Stop Tubing

Use two-stop tubing in standard-sized cartridges and tubing bed sets. Choose from the seven tubing material formulations below. Extension tubing is also available. Tubing stops are color-coded according to tubing ID for quick identification. Stops hold the tubing at the optimal tension necessary for pump head rollers to occlude the tubing. The result is reliable pumping and repeatable flow rates.

3-Stop Tubbing

Three-Stop Tubing

Use three-stop tubing in minicartridges. Choose from the seven tubing material formulations below. Extension tubing is also available. Tubing stops, color-coded according to tubing ID, hold the tubing at the optimal tension necessary for pump head rollers to occlude the tubing. The result is reliable pumping and repeatable flow rates. Three stops give you two sections of tubing to use instead of just one. When one section of tubing fatigues, a fresh section is ready to use.

Nominal Tubing

Nominal Tubing

Use nominal tubing with the quick-change and tubing bed pumps. Choose from seven tubing material formulations below.
