Harvard Apparatus Model 11 Plus Microprocessor Single Syringe Infusion and Withdrawal Pump

The Harvard Apparatus Model 11 Plus is a microprocessor-controlled precision single syringe pump engineered for infusion and withdrawal applications in laboratory and biotechnological research. Designed for high accuracy with ±0.5% precision and reproducibility of ±0.1%, this syringe pump supports both plastic and glass syringes ranging from 0.5 µl to 50/60 ml syringe sizes.

• Flow Rate Range: Ultra-low flow to moderate flow rates spanning 0.0014 µl/hr up to 26.56 ml/min, enabling critical fluid delivery in molecular diagnostics, synthetic biology, and bioprocessing workflows.
• Drive Mechanism: Utilizes a 0.9° step angle motor with 1/4 microstepping and 3,200 steps per screw revolution, providing fine step resolution of 0.33 µm per step and adjustable step rates for precise fluid dispensation.
• Force and Motion Control: Capable of delivering an average linear force of 16 lbs with a pusher travel rate between 0.7 µm/min and 15 mm/min for controlled sample handling or reagent infusion in gene editing or biomanufacturing protocols.
• Memory & Control: Equipped with non-volatile memory allowing storage of all operational settings, facilitating repeatable protocols vital for molecular cloning and live-cell imaging applications.
• Compact Design: Measuring 130 x 229 x 114 mm and weighing 2.1 kg, the compact pump fits benchtop environments requiring precise fluid handling in clinical diagnostics and biomedical engineering.

This single syringe pump is widely adopted in biotechnology research, cell imaging, and molecular biology laboratories requiring robust fluid control, making it essential for workflows involving gene editing reagents, bioprocess automation, and synthetic biology experimentations.
