Agilent 1100 G1311A Quaternary HPLC Pump for Stable Solvent Flow and Gradient Mixing

The Agilent 1100 G1311A Quaternary HPLC Pump offers a stable, virtually pulse-free solvent flow critical for high-performance liquid chromatography applications, including *molecular diagnostics* and *bioprocessing workflows*. Equipped with double-series floating pistons and a precision servo control system, it ensures accurate flow regulation in the range of 0.001 to 10 ml/min with fine increments of 0.001 ml/min. Operational flow range is from 0.2 to 10.0 ml/min, supporting versatile chromatography protocols.

Key technical features include:

• Wide pH compatibility range: 1.0 to 12.5, accommodating a variety of aqueous and organic solvents; note that solvents with pH > 2.3 must be free of acids that corrode stainless steel components.
• Low-pressure quaternary gradient formation: Utilizes a patented high-speed proportional valve allowing precise mixing of up to four solvents, essential for complex gradient profiles in synthetic biology and biopharmaceutical production pipelines.
• Delay volume: Between 800 and 1100 µl depending on backpressure, affecting gradient sharpness and retention time precision.

This quaternary pump is widely adopted in *biomedical engineering*, *cell imaging* workflows, and *chromatographic separation* in *biotechnology applications*, where stable solvent delivery directly impacts reproducibility and sensitivity. The precise solvent flow control and gradient formation make the Agilent 1100 G1311A an essential instrument for labs focusing on *gene editing assays*, *molecular cloning workflows*, and advanced *biomanufacturing process* analyses.
