What is the Harvard Apparatus Pump 11 Elite™?

The Harvard Apparatus Pump 11 Elite™ is a compact, high-accuracy programmable syringe pump that continues the tradition of the Pump 11 series as the leading workhorse infusion pump for life science research. Featuring a high-resolution color touchscreen with an intuitive icon interface, the Pump 11 Elite enables researchers to create, store, and run simple to complex infusion and withdrawal methods entirely on-device — without a PC.

Available in single and dual syringe configurations, the Pump 11 Elite handles syringes from 0.5 µl to 60 ml and delivers smooth, accurate flow from 1.28 pl/min to 88.28 ml/min. With ±0.5% accuracy, 35 lb linear force, and full CE/ETL certification, it is trusted across applications from nanofluidics and electrospinning to mass spectrometry calibration and drug delivery in animal research.

Key Features

• High-Resolution Color Touchscreen: The 4.3" WQVGA TFT touchscreen with intuitive icon-based navigation makes programming fast and accessible, even for complex multi-step methods.
• Wide Syringe Compatibility: Accepts syringes from 0.5 µl to 60 ml (single) or 0.5 µl to 10 ml (dual), with a tight-gripping syringe clamp that ensures secure, slip-free operation.
• High Accuracy and Smooth Flow: Achieves ±0.5% accuracy with flow rates from 1.28 pl/min to 88.28 ml/min, powered by a 0.9° stepper motor with 1/16 microstepping for minimal pulsation.
• On-Pump Method Programming: Store up to two user-defined methods of 50 steps each on the pump, enabling complex protocols (ramps, gradients, I/O interactions) to run without a PC.
• Advanced Connectivity: USB serial port, RS-485 for daisy-chaining multiple pumps, and a 15-pin D-Sub Digital I/O connector for remote and automated control.
• HAPC Compatible: Works seamlessly as a channel within the Harvard Apparatus Pump Controller (HAPC) for centralized multi-pump management.
