The mission of the Microplate Standards Working Group (MSWG) is to recommend, develop, and maintain standards to facilitate automated processing of microplates on behalf of and for acceptance by the American National Standards Institute (ANSI). Once such standards are approved by the MSWG, they are presented to the governing council of the Society of Biomolecular Screening (SBS) for approval for submission to the ANSI. Although sponsored by SBS, membership in the MSWG is open to all interested parties directly and materially affected by the MSWG’s activities, including parties who are not members of SBS.
