Waters 2795 HPLC system with 2487 UV-Vis or 996 PDA

The Waters 2795 HPLC System integrates solvent and sample management with consistent system-to-system performance and high reproducibility. The Waters chromatography system ensures the reliability of results through high injection precision for precise quantification and exceptional retention time repeatability for accurate peak identification. The 2795’s solvent delivery system features quaternary blending with a fixed delay volume for consistent and predictable results, regardless of system back pressure. With pulse-free solvent delivery through the serial flow path without the use of dampeners and accurate flow from online solvent degassing and automated solvent compressibility for, the Waters HPLC system truly features advanced solvent delivery capabilities.

The 2795 HPLC System includes option between the Waters 2487 HPLC Absorbance UV-Vis Detector or the Waters 996 HPLC Photodiode Array Detector. The 2487 is the most sensitive and versatile absorbance detector available for HPLC; it features advanced programmability, dual wavelength capability, unmatched signal-to-noise performance, reduced optical bandwidth, and exceptional linearity. The 996 is the most versatile HPLC photodiode array detector available with the highest sensitivity; it operates exclusively with Waters Empower software to provide complete spectral acquisition and results management.

Waters HPLC systems are built for various applications and routinely used in analytical environments, such as food safety, forensic, research and development, quality control, and chemistry and pharmaceutical laboratories.

All of our equipment is fully tested to perform at factory specifications before being shipped.
