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.

Draws You in to the Series
Format: Paperback
The Stonekeeper is the first volume in Kazu Kibuishi's graphic novel series. Although aimed at middle school, it is good for upper elementary school children, and is enjoyable for adults as well. 2 years after the death of Emily and Navin's father in a tragic car crash, Karen moves her children to the family's old house in a dense forest. Built by Karen's grandfather Silas who then disappeared, it has been abandoned for years. During the first night, they hear a strange noise, and Karen is captured by an Arachnopod, a creature from a parallel world, Alledia. Emily and Navin follow their mother into the parallel world where they find their ailing great-grandfather Silas. He tells Emily about the power of the amulet she found in his house. It is the key to ruling Alledia. Silas expires, but not before instructing his robot and animal minions to aid Emily and Navin. This first volume, besides setting the story arc, narrates the rescue of Karen. Unfortunately, she is poisoned setting up the next volume for finding the antidote. Besides an engaging story with compelling characters, Kibuishi is a fantastic illustrator. As with many exemplar graphic novels the spare text is amplified and much of the story told through his illustrations. The creatures of Alledia are strange enough to pique our imagination, but not so much that they are totally alien in form. After reading Stonekeeper, I am eager to see what happens next with Emily and Navin, and their company.

wow
Format: Paperback
I remember when I read in reviews that kids had gotten sucked into this story and had become fans of this series so quickly.... Well, my daughter resisted till page 13 or 14... but since then she's in it... She's very picky when it is about books and even that she's 9, she started to read in English only a few months ago ( we lived abroad,she reads other language) so she still prefers books that is easy to read. Anyway, get ready, this series is addicted... gooooood :) that is what we need :) I mean, you can complain that this is a comic book but still, at least the child has the book in his/her hand and not a tablet... and at least he/she reads... I'm really happy that I got this book for her.

Wonderful Story, But Small Print
Format: Paperback, Format: Paperback
My son really likes this book. He usually doesn’t enjoy reading much, but this one caught his interest right away. The illustrations are great, and the story is engaging too. He finished the book in just two days! I already bought the second one and am thinking about getting the whole series. The only thing I didn’t like was the size of the letters. It wasn’t very easy for my 9-year-old to read on his own, and sometimes I had to help him.

Shockingly good Little Golden Book
Format: Hardcover
Yeah, this is a Little Golden Book, but in many ways it seems more like something that would be a special addition to a boxed set of the 1980's Teenage Mutant Ninja Turtles cartoon series. It's written as if April O'Neil is talking to the reader directly and it gives a pretty good overview of each of the turtles and their personalities/roles, how the turtles and splinter became mutants, who their enemies are, and references a few reoccurring characters from the series. My kids have been watching a lot of the original series lately and they loved this book. It also wasn't tedious for me to read and wasn't overly long as some of these tv books are. If you have a kid that is a fan of the original series, this is a great pickup. If you know someone who grew up on this series and maybe collects some of the original Turtles stuff, this could be a fun little gift for them to add to their collection
