The Stomacher® 3500 series
Technical
Seward has developed three different Stomacher® machines that provide comprehensive solutions for all blending requirements of large volume applications to meet your needs.
The Stomacher® 3500
The Stomacher® 3500 is used where large volume blending is required. The blending of powders with diluent and the microbiological testing of complete recipe dishes are two popular applications.

The Stomacher® 3500 Biowasher
The Biowasher was originally designed to process the large volume of filter
fibres derived from cartridge filters used in testing water for parasites.
The technique involves filtering very large amounts of water and extracting
the material retrieved to stain and microscopically observe for
cryptosporidium and giardia.
The Stomacher® method for preparing the samples is referenced
throughout the world for this technique.
The Stomacher® 3500 Bioreactor
The Bioreactor is used in the pork industry to prepare samples for analysis for Trichinella. The
machine has a heater element inside the door and the samples of pork meat are digested inside
the bag with enzyme and HCl acid. The resultant slurry is sieved and examined under microscopy
for the presence of the Trichinella parasite.
The Stomacher® technique is the world standard for this application. All pork products imported
into the EU and the USA have to have traceability back to the beast from which the meat was obtained.
Trichenella testing is an essential part of that documentation.
The Bioreactor has a number of additional applications based on its ability to blend and incubate
simultaneously and it can be used in a range of enzyme digestion processes and fermentation
applications.
