Light Obscuration Instrumentview on SAM.gov

The Bioprocess Measurements Group at the National Institute of Standards and Technology (NIST) located at Gaithersburg, MD provides measurement science and standards for robust characterization of biologically or synthetically derived particles that are relevant in the biomanufacturing industry. These particle types can be hard to distinguish, and regulatory guidelines require detailed characterization of these particles in drug products. Industry currently relies heavily on flow imaging microscopy and light obscuration (compendial method) for characterizing these particles in their products. We are requesting an updated flow imaging instrument with light obscuration capabilities to replace two outdated, unsupported systems (Flow imaging and Light Obscuration) which no longer reflect instruments used in industry which limits data comparability and collaboration.
