To complete your Ismatec® pumping system, order three-stop color-coded tubing and extension tubing. Tubing comes in various formulations for almost any pumping application.

Three pre-attached tubing stops give you two sections—when one section of tubing fatigues, a fresh section is ready to use. The stops on the three-stop tubing are color-coded according to tubing ID. Use three-stop tubing with any of the Ismatec® minicartridge pumps and pump heads. Minicartridges withstand pressures up to 22 psi.

FDA-Compliant Viton® tubing features an ultra-smooth inner bore, excellent biocompatibility for sensitive applications, non-cytotoxic, non-pyrogenic, and non-hemolytic, low protein binding. Heat-sealable, bondable, sterile-weldable, and custom moldable for assemblies. This formulation is ideal for pharmaceutical, biotech, and general-purpose lab applications, including sterile filling and processing, cell harvest and media process systems, filtration, fermentation, cell and tissue culture transport. This tubing is opaque black in appearance, features a temperature range of -66 to 135 °C, and offers a tubing life of approximately 1000 hours at 100 rpm.

The overall length of Viton® 97629-series stop tubing is 12" (304 mm). The legacy Ismatec® stop tubing was 180 mm long.
