Pfizer’s Andover, Massachusetts, campus is a large biotechnology manufacturing site with multiple buildings, laboratories and manufacturing suites. The site has the unique challenge of managing and testing a large number of water samples on a daily basis, making it necessary for a large portion of microbiology lab analysts to perform water endotoxin/LAL testing. The Endosafe® Nexus™ robotic endotoxin/LAL testing system combines a proven cartridge-based LAL technology (the multi-cartridge system, or MCS™) with a robotic system that carries sample testing all the way through to completion. This system increases laboratory throughput and efficiency while reducing potential pipetting variability and data entry errors with its sample bar code reader and ability to communicate with Labware LIMS.
