Quality Control

    Where robust manufacturing meets comprehensive chemistry and microbiological QC testing

    Measurement is at the heart of quality control in the pharmaceutical chemistry business. That is why Exelead takes its investment in quality control equipment and procedures so seriously. We have fully equipped our facilities to monitor the integrity of your chemical compounds, in every stage of product development.
