Stomacher® 400 Circulator


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 homogenization 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 Stomacher 400 Circulator paddles create a washing effect driving more organisms in suspension thereby providing a better homogenized sample for analysis.

Why the Stomacher® 400 Circulator

  • Improved organism recovery with the patented curved shape of the Circulator paddles over older square paddle designs
  • No risk of cross contamination between samples
  • Durable and reliable
  • Control panel with programmable settings or ‘hands-free’ auto-run
