The Stomacher® 400 circulator

for food microbiologists


The Stomacher® 400 Circulator is the world’s leading laboratory paddle blender for food microbiologists. The Stomacher® Circulator principle improves organism recovery over older square paddle designs by enhancing the stirring and extrusion forces applied to the sample and in doing so driving more organisms into suspension for analysis.

Meeting the food safety and quality demands of today’s microbiologists

Whatever method you use to enumerate and identify bacteria, yeasts and moulds in your laboratory, thorough reproducible homogenisation of the sample is the first and most
critical step.


Numerous studies have demonstrated the Circulator enhancement as a positive benefit to pathogen testing procedures in traditional microbiology and PCR based techniques.


As the sample is crushed during operation, the patented curved shape of the Circulator paddles create a washing effect driving more organisms in suspension thereby providing a better homogenised sample for analysis.
