Cryogenic grinding of plant and animal tissue is a technique used by microbiologists. Samples that require extraction of nucleic acids must be kept at −80 °C or lower during the entire extraction process. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples. [2]

Cold or cryogenic grinding is the ideal solution for such samples. This entails the use of grinding aids, such as liquid nitrogen (-196 °C) or dry ice (-78 °C), that embrittle the sample by cooling and enabling breakage to occur more easily. This also allows the volatile components of the sample to be preserved.
