DEMETER™ Food Microbiology Media Preparation System

DEMETER Food Microbiology Media Preparation System

The DEMETER™ is a highly traceable food microbiology testing lab instrument that automates the Media Preparation steps in the food testing process, resulting in both higher lab productivity and increased testing accuracy. DEMETER™ delivers versatile flexibility for a lab, allowing it to run multiple tests with different media, and eliminating the need for an autoclave to heat and sterilize the test media. The system features a bar code scanner that records sample information from each test into an internal buffer that can be interfaced to a lab information management system (LIMS). This feature streamlines the recordkeeping needed to maintain yearly lab accreditation per ISO 17025:2005 standards, and to the increased regulatory compliance resulting from the passage of the Food Safety Modernization Act (FSMA).
