Curved paddles crush and stir the sample

Driving more microorganisms into suspension and providing a better homogenised sample for analysis, the Stomacher 400 Circulator laboratory blender has a combination of curved paddles, a central island baffle and a round bottomed Stomacher bag. The system improves organism recovery over older square paddle designs by enhancing the stirring and extrusion forces. In operation the paddles crush the sample but also circulate the bag contents. The circulating action enhances the washing action applied to the sample debris as it is crushed. The result is more organisms driven into suspension. These heavy duty machines are built to industrial standards and are suitable for large volume food microbiology like sample preparation of meat for E.coli testing.
