Agilent 1260 Infinity II HPLC G7104C Flexible Pump with Dual-Piston, Servo-Controlled Variable Stroke
Product Description
The Agilent 1260 Infinity II HPLC G7104C Flexible Pump is engineered for high-precision solvent delivery in advanced high-performance liquid chromatography systems. Featuring a dual-piston, servo-controlled variable stroke design, it ensures smooth flow with active damping, supporting a flow range of 0.001 to 5 mL/min adjustable in 0.001 mL/min increments. This pump delivers high flow precision (≤ 0.07% RSD) and accuracy (±1% or ±10 µL/min) critical for robust gradient formation in complex analytical workflows.
Key technical features:
- Low pressure pulsation ensures stable solvent delivery, vital for reproducible biochemical separations and molecular diagnostics.
- Quaternary gradient capability with a high-speed proportioning valve allows precise mixing of up to four solvents, supporting complex solvent systems used in biotechnology and synthetic biology research.
- Automatic compressibility compensation enhances system performance across various solvent types, improving method robustness in bioprocessing and clinical diagnostics applications.
- Integrated 4-channel degassing unit reduces gas interference, optimizing chromatographic resolution and sensitivity.
- Automatic purge valve streamlines maintenance, reducing downtime in biomanufacturing and pharmaceutical analysis.
- Extensive communication interfaces (CAN, LAN, RS232C) facilitate system integration and remote operation within automated workflows.
- Advanced safety features including leak detection and automated shutdown protect instrument integrity in demanding laboratory environments.
- GLP-compliant functionality enables early maintenance alerts and electronic record management, ensuring traceability and compliance in regulated molecular biology laboratories.
This pump is widely used in biotechnology, biomedical engineering, and molecular diagnostics, especially for workflows requiring precise solvent delivery and gradient formation, such as gene editing assays, protein purification, and synthetic biology investigations. Its ability to maintain consistent solvent composition with low delay volume makes it a critical component in biopharmaceutical production pipelines and essential for molecular cloning workflows.
