Refurbishment process


During evaluation, we review the unique service history for each instrument that comes in for refurbishment. A careful appraisal of each instrument, based on its history, is made to determine if the instrument will meet our high levels of quality. Field service engineers and product support specialists evaluate the instruments and recommend any required updates. They then carefully package and crate the instrument for the trip back to our factory refurbishment centers to avoid any damage or injury to the instrument.


Our certified field service engineers will de-install, crate, and ensure decontamination of previously-owned systems. Rest assured that all Thermo Fisher mass spectrometers have been thoroughly evaluated and refurbished in our refurbishment and reconditioning centers, following stringent quality standards.


Once in our factory refurbishment center, instruments undergo a thorough assessment and evaluation before they enter the refurbishment process to identify requisite updates, upgrades, and modifications. Included in the assessment are PCB revisions, hardware assessments, and software application upgrades.


There is no compromising on quality. All of our systems are refurbished according to a stringent, quality-controlled refurbishment process. Systems are disassembled and thoroughly inspected with installation of only new parts. The systems then undergo rigorous testing procedures that require them to meet all manufacturing testing specifications.


Installation is completed by our factory-trained, certified Unity Lab Services field service engineers, all to OEM specifications. All systems are installed to meet new instrument installation specifications, so you can be confident your instrument will meet your high standards for performance and reliability. Our Unity Lab Service engineers will ensure you will get your system operational and producing data in the shortest time possible.

“ Buying a refurbished Q Exactive from Thermo [Fisher] was the right decision ... We got all the right instruments for the applications within the budget. It has solid performance, good mass accuracy and great resolutions. ”

— Julia C. Guo, Senior Research Scientist, Global Structure Analytics, BASF Corporation

“ There were some considerations to buy 3rd party, however, a good relationship with instrument vendors and having access to a large repository of application engineers and support personnel made the decision easy. I should say that this already has paid off even though we've had the instrument only for a few months. ”

— Dr. Bernhard Vogler, Associate Prof. of Chemistry At University of Alabama in Huntsville.
