Overview

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
  • Countdown of processing time
  • Removable door for easy cleaning of paddle chamber
  • 3 year warranty and 10 year service support

The Circulator allows for easy and effective processing of multiple samples, without risk of cross contamination. The quality of the Stomacher® build and components impart durability and reliability, 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.

FAQ

What is the voltage of the Stomacher 400 Circulator?

The Stomacher 400 comes in 110 V by default, but if you prefer a 230 V Hz version it is available at the same price. Please inquire for details if you would like a Stomacher 400 in 230 V. (Both versions are universal frequency, 50 / 60 Hz.)

 

Can the Stomacher 400 be calibrated?

There is no protocol or built-in functionality for you to calibrate it yourself, but the unit can be sent back to Seward for re-calibration. This does incur a cost.

The Best Diapers for My Baby!

I absolutely love these Huggies Little Snugglers diapers. They are super soft on my baby’s skin and have not caused any irritation. They absorb very well and help prevent leaks, even overnight.I also like how perfectly they fit and how comfortable they seem for my baby. The quality is excellent, and the pack comes with a great quantity. I will definitely keep buying them and highly recommend them for newborns and small babies.

Gentle protection for tiny beginnings
Size: Newborn, Unit Count: 31
Huggies Size Newborn diapers have been a lifesaver during those first precious weeks. They’re incredibly soft and gentle on delicate newborn skin, which gave us peace of mind from day one. The fit is excellent, snug without being too tight and the umbilical cord cutout is a thoughtful feature that makes healing easier and more comfortable for the baby. We’ve experienced very few leaks, even during overnight use, which is impressive for newborn diapers. Overall, Huggies Newborn diapers offer reliable protection, comfort, and quality. They’ve made those early sleepless nights just a little bit easier, and we wouldn’t hesitate to recommend them to other new parents.

Great Product-Love These
Size: Newborn, Unit Count: 31
We have tried other name brand diapers over the years and people rave about other brands, but our experience with other brands is not good. Even the hospital doesn't use this brand and baby's onesie kept getting wet. They were folding their Pampers down at top for umbilical cord where Huggies have cut out for umbilical cord. Our personal experience is other name brand diapers seem to leak with our babies, and these stay snug and keep clothes and baby dry. When it says 100% leak proof and all-around blowout blocker it's factual for us and our babies. They are easy to use and durable. We have babies with sensitive skin and there is no irritation with these diapers.
