This robust new laboratory blender is specifically designed for large volume food testing procedures, such as the FDA's Bacteriological Analytical Manual (BAM), where 375g composite samples are required for the microbiological analysis of food.
The heavy duty Stomacher 4500 complements the Stomacher 400 Circulator. This new blender provides food laboratories globally with a high performance, high quality blender capable of homogenizing sample volumes ranging from 1000 to 4500mL. Highly efficient, the new Stomacher 4500 also has programmable settings to ensure the best preparation protocol is used for microbial extraction, depending on the food sample under analysis.
The new Stomacher 4500 is the perfect tool for extraction from 375g composite samples, as defined by protocols such as the FDA’s BAM for the preparation of Category III food samples for Salmonella detection [1]. Here the composite sample should be 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 new large volume Stomacher enables food manufacturers to combine 15 x 25g (375g) analytical units, rather than testing each unit individually, so saving time when analyzing lower risk food products.
