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.

Just lovely
Size: 8.5" x 5.8" x 1.9", Color: Orange
Purchased this several months ago and liked it, but I had received so many complements on this tray since then I had to submit this review. The tray is sturdy and put together well, and the size is exactly what was given before purchase.

A Stylish and Functional Addition to My Décor!
Color: Gray 1 Pack, Size: 8" x 8" x 1.8", Color: Gray 1 Pack, Size: 8" x 8" x 1.8"
I recently purchased the ZHEM Valet Tray for Men in Dark Gray, and I couldn't be happier with this product. It's become an indispensable part of my daily routine and home décor. The design and craftsmanship of this tray are outstanding. The dark gray color is elegant and complements my furniture perfectly. It's not just a valet tray; it's also a decorative piece that adds a touch of sophistication to my nightstand and dresser. The size (8x8x1.75 inches) is ideal for holding my daily essentials like my watch, perfume, keys, and even napkins. I appreciate the versatility - it serves as a decorative piece, an organizer, and a functional tray all in one! The quality is top-notch, and it feels sturdy and well-made. It's also easy to clean, which is a big plus. Overall, the Tray has exceeded my expectations. It's a stylish and functional addition to my décor, and I highly recommend it to anyone looking for a versatile and attractive tray for their home. Five stars! ⭐⭐⭐⭐⭐

Super cute landing space for keys
Color: White 1 Pack, Size: 8" x 8" x 1.8", Color: White 1 Pack, Size: 8" x 8" x 1.8"
I always have trouble finding my keys and so it’s been very helpful to have a dedicated spot to easily throw them in when I get home. At first I thought it would be too big but it’s the perfect size for two wallets and keys, and it’s good quality albeit a bit expensive. The gold isn’t too shiny either, it’s a nice touch and it really reduces the look of clutter on your surfaces and helps it look more organized. It also doesn’t slip around.
