Harvard Apparatus Introduces New Line of Pumps

Published December 12, 2012
Harvard Apparatus has introduced a new line of peristaltic pumps. Peristaltic pumps aid in moving fluids via a peristaltic motion, the motion by which gastrointestinal muscles move substances through its channels such as the swallowing mechanism in the esophagus. The Harvard Peristaltic Pump series devices are remote-controlled and programmable.

Some of lines’ key features include, according to the company, the remote controlled design and sealed pump head, which make the pumps ideal for use in incubators and fume hoods; Interchangeable pump heads allow for economical ease of use over a broad flow rate range; pre-programmed profiles for constant flow, flow ramps, pulsatile flow, and concentration based fluid delivery; and a library of tubing sizes stored in the pump’s memory, intended to minimize setup time.

The pumps consist of a control unit, tethered pump head, and cartridge/cassette and some sample tubing. They can reportedly deliver solutions over a range of flow rates from 0.001 to 1,500 milliliters per minute depending on the pump head used.

The pump will automatically rotate at the proper RPM for the tube selection and flow rate chosen, claims the company. To further increase the accuracy, the line also offers a rapid calibration routine to further optimize flow accuracy by entering a measured volume of fluid collected.

Harvard Apparatus, part of the Harvard Bioscience group of companies, is base din Holliston, Mass. The company focuses on specialized bioscience research products including syringe pumps, ventilators, pulsatile blood pumps, transducers, amplifiers, recorders, and glassware.
