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.

Not that Jack Black!
Size: 4 Piece Set
I bought this set assuming it was the actor/musician Jack Black’s skincare line. I figured a bearded celebrity would know all about quality beard care products. But actually it is not even named after a real person, it’s just a brand name. In fact, Jack Black the celebrity said he tried Jack Black products and they gave him a rash! Not a big deal though. I haven’t had such a reaction. The products smell fine, not overbearing, and seem to be working well. Cons: not exactly economical since it’s very small tubes. The beard oil pump is easy to overdo— Press too hard on the pump and you’ll end up with too much oil on your hands. A little goes a long way.

Did not realize beard lube and wash are mini/travel size but that’s my fault for not checking.

Never have I felt my beard this soft after using this beard oil…
Size: 4 Piece Set
I’m usually not the dude to leave a review on a product, but the second I hop out of the shower and tried the beard wash and beard oil, I was shocked. Out of all the other beard oils and beard wash products i’ve used, this has to be the best result so far. For the price, It can be expensive, sure. But it’s the only one you need. I don’t think i’ll ever go on a search for beard oil or wash ever again. This product is great!

Great kit for beards!
Size: 4 Piece Set
I had struggled with an itchy face/beard forever. Just thought my face was dry so I used lotion but it did not resolve the itch. Did some research and saw this brand recommended by multiple sites. I decided to give it a try. Since using these products, my face/beard no longer itches! Shaving (cleaning up my beard edges) with the shave cream seems to feel much smoother too. It feels as it softens the hairs which then requires less effort to shave off. Follow this up with the good and lightly scented beard oil to leave a smooth feeling, no-itch beard. Would definitely love bigger sized containers but I would definitely recommend these Jack Black beard products.
