Seward Stomacher^® Laboratory Blenders

Blend and homogenize within sealed processing bags – eliminating cross-contamination and cleaning between samples

       Small footprint offers convenient placement on your lab bench

       Increase productivity – no need to clean equipment between processing, simply discard bags after use

       Paddle design processes materials that cannot be handled by conventional lab blenders

The unique action of the Stomacher uses paddles to homogenize samples through a combination of crushing and stirring forces.

Gamma-irradiated sterile disposable bags(order separately) allow you to homogenize and transport samples without changing

containers or handling sterile samples.

Stomacher 400C processes larger sample volumes from 80 to 400 mL. It features one-touch user-programmable time, three

paddle speeds, and "hands-free" auto-run. The unique patent-pending curved paddle design produces homogenization through

a combination of crushing and stirring. During operation, the curved paddles and an island baffle mold the bag contents into a

tubular ring for vigorous stirring and circulation of the sample from top to bottom, extracting more organisms into suspension than

any other blending process. Round-bottom blender bags without corners or creases maximize the efficiency of the curved

paddle design.
