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.

A+ mount for 4Runners
This is the best phone mount I've ever had. Got it for my 2021 4Runner. Very strong, doesn't come loose, easy to place and remove the phone from the mount. Can't recommend enough.

Best Phone Mount EVER!
I searched the Toyota forums and consistently saw this item mentioned as one that would not move on bump roads or even over time on smooth roads. It is the best and must secure mount I have ever used. It fits perfectly on was designed not to obscure the view. I have recommended this brand to everyone that I have talked to about mounts since I got. Very easy to install also!

Works well, looks stupid with the logo display
This fits well in the vent frame and I am still able to close my vent. I really like the mount cause it solves a huge problem of where to put my phone securely... but I also hate it as well, because of the ugly logo on the face of it. "Batdiary"? Seriously? If I keep it I will look for a way to get rid of (or cover up) the extremely unattractive logo they selected. It makes it (and my trucks interior) look loke something for a child. I give it 5 stars because it deserves better than the 3.9 it had at the time of posting this. But for the love of everything clean and classy but still needing a mount, get rid of the bat logo!
