Miniature Peristaltic Pumps

The 400 F/A matchbox-size peristaltic pumps are smaller and more economical than syringe pumps.

Designed for sample preparation, the pumps are suitable for automated laboratory applications such as dispensing and collecting samples and reagents. The self-priming unit accommodates 0.1- liter to 350-gpm flow rates, withstand pressures to 232 psi, and provide up to a 30-ft suction lift. There are no internal universal joints, valves, dead corners, or glands to impede flow. The pumps are reversible for back flushing lines.
