Stomacher 400 Circulator

Why the Stomacher® 400?

  • Enhanced organism recovery over square paddles
  • Durable & reliable, designed for consistent use
  • The gold standard in laboratory blenders
  • No cross contamination between samples
  • Simple to clean and requires minimal maintenance
  • 3 year warranty


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.

The Stomacher® Bag Range has been designed to fulfil all applications from blending, stirring and storage of samples, with no risk of cross contamination between samples. The Stomacher® 400 Bag Range caters for both the Circulator bag (round-bottom) designed bags, and the Classic (square-bottomed) for the older square paddle designed Stomachers®.

Our Stomacher® bags are made from high quality food grade virgin LDPE granule,extruded to 65µm film thickness. All Stomacher® Bags are irradiated sterile. A certificate or irridiation is available upon request.

Only genuine Stomacher® Bags carry the Seward quality mark.
