The Welch 3100 peristaltic pump is ideal for laboratory research and development, pharmaceutical manufacturing, commercial food processing, environmental sampling, and general industry applications. Pumps work with moving liquids, gases, solids, and mixed-phase media.

The 3100 features bi-directional speed control with a reversible motor and maximum flow control button. A unique head design, combined with an easy-to-use cartridge assembly, eliminates the need for disposing of several feet of tubing when only a small portion of the tubing has worn out.
