A versatile Stomacher® designed for the BAM testing procedure as well as large volume blending and extraction. The Stomacher® 4500 BAM delivers the quality of testing expected from Seward Stomacher® lab blenders. Initially designed in response to the introduction of the Bacteriological Analytical Manual (BAM) by the US Food and Drug Administration (FDA), the Stomacher® 4500 BAM is ideal for the BAM large volume testing procedure. The Stomacher® 4500 BAM is the perfect tool for extraction from 375g composite samples, as defined by the FDA’s BAM protocols for the preparation of Category III food samples for Salmonella detection. Here the composite sample is combined with its pre-enrichment medium at a 1:9 sample-to-broth ratio (375g sample/3375mL pre-enrichment) with no risk of spillage. Consequently, the large volume Stomacher® 4500 lab blender enables food manufacturers to combine 15 x 25g (375g) analytical units, rather than testing each unit individually, so saving time when analysing lower risk food products. As the demand for faster, cheaper, easier and more accurate tests continues to grow for large volume sample preparation requirements, the Stomacher® 4500 BAM offers a solution for applications in food microbiology, forensic residue and hygiene analysis as well as environmental applications.
