Stomacher® 3500

A versatile range of tools for large volume blending and extraction

The Stomacher® 3500 Series provides a versatile range of tools for large volume blending and extraction where all washing solution or solvent needs to be retained for analysis. This heavy duty range of machines are built to industrial standards and often used in applications for large volume food microbiology, forensic residue analysis and testing of waterborne parasites.

WHY the Stomacher® 3500 Series

  • 400-3500ml sample capacity
  • Suitable for wide range of food applications
  • Cryptosporidium and Giardia testing
  • Trichinella testing
  • 3 year warranty and 10 year service support

The Stomacher® for large volume applications

The standard 3500 Stomacher® has been developed and widely used for blending large volumes such as powder, chocolate and sterility of disposable products (e.g. diapers). Similarly the Stomacher® method developed through the Biowasher and Thermo are referenced throughout the world as the standard for analysis in their respective applications.

The Biowasher was originally designed to process the large volume of filter fibres derived from cartridge filters used in testing for waterborne parasites such as cryptosporidium and giardia.

An added heater element allows the Thermo to test for Trichinella, an essential documentation requirement for the sale of pork products. The Stomacher® technique is the world standard for this application.

Stomacher® 400 EVO

he World’s leading laboratory blender for food microbiologists has EVOlved.


Introducing the Stomacher® 400 EVO, the new sample preparation solution that combines stress-free working with for your laboratory

The Stomacher® 400 EVO

  • Unique one-touch bag loading system
  • Quiet and efficient blending
  • Easy clean interior with removable paddles, drip tray and access to paddle chamber
  • Designed to work with our new Eco bag range for extra savings
  • Same reliability and quality you expect from a Seward Stomacher®

The all new design of the Seward Stomacher® 400 EVO combines the gold standard attributes of the original Stomacher® 400 with improved, easy-to-use features. Providing maximum performance while minimising noise and consumable waste.

Easy to use

  • Unique ‘one touch’ bag loading system minimises sample bag handling, saving time and reducing the risk of sample contamination
  • Simple programmable screen display enables complete control of processing, for consistent results with minimum effort


Easy to clean

  • Front cover and strike plate can be removed to provide easy access to paddle chamber and detachable paddles for simple and thorough cleaning
  • Removable drip tray allows for easy cleaning, saving time in day-to-day use


Quiet Operation

  • Double aperture seal, isolated chassis, and fully enclosed casing result in silent operation, reducing stress and disruptions to other lab work
  • Rubber base with anti-vibrational technology eliminates bench movements and reduces noise

 Saves Costs

  • Designed for use with both standard and new Stomacher® 400 Eco bags
        •  Quick and simple Eco paddle conversion can save up to 30% in consumable cost and significantly reduce plastic waste



Stomacher® 400 Circulator

The world’s leading laboratory paddle blender for food microbiologists

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

Whatever method you use to enumerate and identify bacteria, yeasts and moulds in your laboratory, thorough reproducible homogenisation of the sample is the first and most critical step.


As the sample is crushed during operation, the patented curved shape of the Circulator paddles create a washing effect driving more organisms in suspension thereby providing a better homogenised sample for analysis.
