Seward Stomacher® 400 Circulator

The world’s leading laboratory paddle blender for food microbiologists

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
  •     Countdown of processing time
  •     Removable door for easy cleaning of paddle chamber


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.

Manufactured to industrial standards the Circulator allows for easy and effective processing of multiple samples, without the risk of cross contamination. The Stomacher® owing to the quality of build and components, is highly durable and reliable, ensuring consistent homogenisation during frequent use.
The digital control panel provides simple control of processing features such as paddle speed and processing time, essential for consistent results. These features are programmable for repeatable homogenisation protocols.

Globally referenced by thousands of protocols in food microbiology, the Stomacher® 400 Circulator is the gold standard in laboratory blenders.
The unique patented Circulator paddle design improves organism recovery over older square paddle designs by enhancing
the stirring and extrusion forces applied to the sample, driving more organisms into suspension for analysis.
