✅ This Waters Alliance System has been Fully Recertified and Tested to Perform at Manufacturer Specifications.
Product Description
The Waters 2695 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 2695’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 2487 UV Detector 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.
