The Stomacher® 3500 Thermo Bioreactor is used in the pork industry to prepare samples for the detection of Trichinella.

The machine has a heater element inside the door and the samples of pork meat are digested inside the Stomacher® bag with enzyme and HCI acid. The resultant slurry is sieved and examined under microscopy for the presence of the Trichinella parasite.

The Stomacher® 3500 Thermo Bioreactor is compatible with a range of Stomacher® bags. The BA6042 Standard 3500 bag (60 microns), suits standard operations. The BA6042/HD Heavy Duty bag is designed to serve resilient applications with a greater bag thickness of 80 microns. As well as the latest in innovation, the new Autoclavable Stomacher® 3500 bag is the first paddle blender bag designed to be autoclavable for sterility methods post-testing.

Seward is at the forefront of the microbiology industry, providing laboratories with the products necessary for sample preparation.

Home of the Stomacher®, it is the most highly referenced brand name in food safety and life science sample preparation in scientific publications.

Focusing on transparency, accuracy and traceability, the Seward range helps to produce accurate, repeatable and robust results.
