Homogenization

Stomacker In order to cultivate bacteria from certain types of samples (including food and feed) it is important to disperse the sample in the dilution broth without damaging the bacteria. A Stomacher® is an apparatus used for homo­genisation of samples in food micro­biology. A large amount of viable microorganisms can be released from different kinds of food samples by this method. The apparatus does not have to be sterilized because the samples are contained in sterile plastic bags to which sterile medium is added.

A. The homogeniser, which is loaded with a plastic bag containing the sample and culture fluid
B. Rack for the plastic bags during the incubation
C. Rack, which is used during the weighing of sample material and addition of culture medium
D. Sterile plastic bags in the homogenizer and for the incubation
