Description
Harvard Apparatus 975 Compact Infusion Pump Multi-Syringe 115V 60Hz USA
The Harvard Apparatus Model 975 is a benchtop mechanical syringe infusion pump designed for precise, controllable fluid delivery in laboratory and research settings. It operates on a motor-driven leadscrew mechanism that advances syringe plungers at a selectable rate, making it suitable for applications requiring repeatable volumetric flow. The pump is infusion-only and accepts multiple syringes simultaneously across its adjustable syringe rail.

Applications
Harvard Apparatus syringe infusion pumps are standard tools in pharmacology, neuroscience, physiology, and biochemistry research labs. The Model 975 is used to deliver precise volumes of reagents, drugs, buffers, or other fluids at controlled, repeatable flow rates over extended periods. Common applications include in vitro perfusion experiments, drug infusion studies, and microfluidic or analytical chemistry setups where steady-state flow is needed. The multi-syringe capability allows parallel delivery from several syringes simultaneously, useful when multiple channels or fluid streams are required. Harvard Apparatus (based in South Natick, MA) has been a leading manufacturer of syringe pumps for academic and industrial research since the mid-20th century; the 975 model is a classic mechanical-drive design from that era, valued for its simplicity and durability in environments where electronic programmability is not required.
This Harvard Apparatus 975 Compact Infusion Pump has been inspected and is in good used condition. The unit powers on and the flow rate controller functions; however, flow rate accuracy has not been independently verified, so buyers who require precise calibration should factor that in. The white metal housing shows general age-related wear consistent with lab use, and the front panel flow rate chart label has some peeling/damage at the lower left corner as visible in the photos. Please view our photo set and contact us if you have any questions.
