Pfizer’s biotechnology site in Andover, Mass., has used Charles River Laboratories’ Endosafe® Multi-Cartridge System (MCS™) for testing routine water samples in the QC microbiology lab since 2010. Although this system reduces the individual sample testing time from 60 to 15–20 minutes, each unit can only process five samples at a time. In order to process all samples received on a given day, analysts were often required to rely on three MCS™ systems and remain at the bench for up to six hours. This led the site to perform a beta evaluation of Charles River Laboratories’ Nexus™ testing system in 2013.
