Homogenizers for Mixing, Dispersing, and Emulsifying
The maximum volume of microbial suspension per hour that can be treated by the larger commercial machines is 4,500 liters for high-pressure homogenizers versus about 1,200 liters for bead mills. Even larger capacity high-pressure homogenizers are available but their efficiency in disrupting microbial cells has not been documented.
