Syringe Pumps Application Selection Guide Cell Biology Cellular studies typically involve the injection of very small volumes under controlled conditions. Several models offer a foot pedal accessory to start/stop flow on command. • For cellular microinjections of plasmids, viruses, and the like, see either the Pump 11 Pico Plus Elite on page 14, PHD ULTRA™ Nanomite on page 28 or the Pump 11 Elite Nanomite on page 16. Mass Spectrometry Calibration and Electrospray Ionization Calibration and Electrospray Ionization Where precise volume delivery and pulse free flow are required for optimum instrument calibration or solvent elimination, the Pump 11 series has long been the industry standard for manufacturers in OEM configurations and end users. See the Pump 11 Elite on page 11, and Pump 11 Pico Plus Elite systems on page 14. Additionally, use of the gradient capabilities of the Pump 11 Elite or PHD ULTRA™ Series allows for automated multi-point calibration when performing GLP studies. SYRINGE PUMPS Application Selection Guide MALDI-TOF Matrix Addition Using the Nanomite with its detachable delivery and electronics allows for easy placement of the syringe over the target to facilitate the dispensing of the appropriate matrix. See the PHD ULTRA™ Nanomite on page 28 or the Pump 11 Elite Nanomite on page 16.

Harvard Apparatus pumps are used in creating Nano and Micro scale polymer fibers in a high voltage field. The stability of flow and flexibility of use, in the PHD ULTRA™ series pumps, makes it easy to alter the variables relating to successful electrospinning. Our pumps include a grounded power supply and can be supplied with a grounding strap, which will shunt any high voltage arcs to ground.
