Cryogenic grinding

Cryogenic grinding of plant and animal tissue is a technique for the microbiologist. Samples that require extraction of nucleic acids must be kept at -80 ºC or lower during the entire extraction process. Utilizing Freezer/Mills will maintain the sample temperatures well below these critical temperatures during the automated grinding sequence. For samples that are soft or flexible at room temperature, cryogenic grinding may be the only viable technique for processing samples.
