Stomacher lab blenders offer fast, reliable blending and homogenizing of laboratory samples through their unique action by which paddles apply pressure to a sample within a sterile, disposable bag. Contents are blended and homogenized, and deep-seated organisms are effectively washed out. Laboratory samples can be collected, transported, processed, and disposed of without handling. Ideal for processing food microbiology samples; removing viruses and bacteria from tissues and organs; testing sterility of creams, ointments, and dry powders; and removing organisms from swabs, filters, tissue biopsies, and fecal samples. The Stomacher 3500 is designed for blending large volumes. Mixing Capacity: 1000 to 3500ml.
