Harvard Apparatus 55-2222 Digital Syringe Pump for Precise Fluid Delivery
Product Description
The Harvard Apparatus 55-2222 Digital Syringe Pump is a precision fluid delivery system widely used in biotechnology, molecular diagnostics, and bioprocessing workflows. Designed for accurate control of infusion and withdrawal rates, this digital syringe pump supports syringe volumes ranging from 0.5 µL up to 140 mL.
Key technical features include:
- Flow rate range: 0.002 µL/hr to 55.1 mL/min, adaptable for low-volume microfluidic and high-throughput applications.
- User interface: LED display with numeric keypad allows precise input of syringe diameter and flow parameters.
- Units of flow: Configurable in µL/hr, µL/min, mL/hr, and mL/min to suit diverse experimental protocols.
- Optical encoder: Ensures accurate monitoring of lead screw rotation for maintaining constant flow rates during long-term biomanufacturing processes.
- Safety indicator: Run LED flashes if syringe plunger motion ceases unexpectedly, critical for maintaining flow consistency in gene editing and synthetic biology research.
- Connectivity: RS-232 remote interface facilitates integration into automated bioprocess control systems and laboratory instrumentation networks.
The 55-2222 model is essential for molecular cloning workflows requiring reproducible and stable fluid handling and is popular among researchers conducting live-cell imaging, fluorescence analysis, and biomedical engineering studies. This syringe pump’s robust build quality and versatility make it a standard choice in clinical diagnostics and biopharmaceutical production pipelines.
Note: Syringes are not included but can be sourced separately depending on experimental needs.
