HPLC Pump Overview

The Refurbished HPLC Pump Shimadzu LC-20AT is part of the advanced Prominence series, engineered for high precision solvent delivery in analytical laboratories. It is widely used in pharmaceutical, chemical, environmental, and biotechnology applications where accurate and reproducible chromatographic results are essential.

This pump features a parallel dual plunger mechanism, which minimizes pulsation and ensures stable solvent flow even at high pressures. It supports both isocratic and gradient elution when integrated with compatible systems.

The LC-20AT is designed to handle high backpressure conditions and offers excellent flow accuracy, making it suitable for complex analytical separations.

Technical Specifications

• Flow rate range: 0.001 – 10.000 mL/min
• Maximum pressure: ~400 bar (40 MPa)
• Flow accuracy: ±1%
• Flow precision: RSD ≤ 0.1%
• Pump type: Parallel dual plunger
• Solvent delivery: Isocratic (gradient via system integration)
• Degassing: Compatible with external degasser
• Display: Digital LCD with status indicators
• Control: Keypad and system integration support

Working Principle

The pump operates using a parallel dual plunger system, where two pistons work alternately to deliver solvent continuously. This design ensures:

• Minimal flow pulsation
• High pressure stability
• Consistent flow under variable load

This results in improved chromatographic resolution and reproducibility.
