Before researchers and lab assistants are able to analyze samples, they usually
have to prepare the material first. Mixing, crushing, dispersing or homogenizing
processes tend to be quick. The cleaning of the machine, however, is time
consuming and can be dangerous when working with toxic substances. But
now, thanks to the new, hermetically sealed, disposable tube system, contact
with the sample material is minimized and sample processing time is decreased.
