Agilent’s Certified Pre-Owned Instruments deliver performance and reliability to your lab at an exceptional value. Our pre-owned instruments undergo a comprehensive refurbishment process by trained Agilent engineers that includes factory updates, cosmetic upgrades, new ship kits and start up consumables, and performance testing to meet the same checkout specifications as a new instrument. All instruments come with a one year warranty. For most listings, installation and familiarization is included.
