AELAB High Performance Liquid Chromatography K2025 Pump – Precise & Reliable

The AELAB K2025 High Performance Liquid Chromatography Pump is engineered for reliable, high-accuracy solvent delivery in analytical HPLC workflows. With validated design architecture and high-quality components, the K2025 passes formal reliability testing to ensure long-term stable operation. The precision and accuracy of the results are guaranteed with unique pumping and sampling technology, high-sensitivity control, and advanced data-processing software.

The operation of the AELAB K2025 Pump is optimized for user-friendly performance, enabling efficient method setup, solvent management, and long-term data traceability. The system fully complies with FDA 21 CFR Part 11 and supports secure database-based audit trails.

⚙️ Design & Construction

The K2025 Pump incorporates a high-strength alloy steel cam processed with high-frequency heat treatment to achieve a wear-resistant surface hardness above 55 HRC. A high-power customized motor, Japanese NSK bearings, and an independent air duct ensure long service life. The piston drive system uses self-lubricating, wear-resistant German materials with anti-locking rifled internal wall design.

The patented suspended floating plunger (Patent Number: ZL 2020 2 1896102.3) adapts automatically to working conditions, reduces eccentric wear, and supports automatic plunger cleaning for improved sealing performance.

🔬 Working Principle / Testing Method

The AELAB K2025 delivers solvents using a reciprocating tandem plunger system with real-time pressure dynamic suppression technology. This minimizes pressure pulsation and ensures accurate gradient formation for binary and quaternary pumping modes. Flow control is regulated digitally across the 0.001 mL/min to 10.000 mL/min operating range, enabling reproducible retention times with ≤0.2% repeatability.

💡 Key Advantages

• Dynamic pressure suppression for stable gradient formation
• Automatic plunger rinsing to prevent crystallization and extend seal life
• 4-channel solvent selection valve for automated solvent switching (P2)
• Independent 4-channel gradient proportioning valve for easy maintenance (P4)
• Enhanced cam and piston materials for increased mechanical durability
• Rapid purging via both the workstation and the instrument panel
• Realtime pressure monitoring for consistent chromatographic performance

🔗 Connectivity & Integration

The K2025 integrates with chromatography workstation software for pump control, gradient programming, data logging, and pressure monitoring. Full database mode supports FDA 21 CFR Part 11 compliance with secure storage and traceability.
