Grinding occurs in a mortar and a grinding jar made from the same material. Mixer Mill. This type of mill is ideal for ambient and cryogenic grinding of biological samples, plant material, plastics, pharmaceuticals and chemicals. Mixer mills grind samples by imparting motion to the container in which grinding elements have been placed.
Sample drying and grinding (plant) Moist plant samples are dried at 65°C until crisp. Samples are then passed through a stainless steel grinder with 20 mesh sieve and mixed thoroughly. Ground samples can be stored at room temperature, but must be redried at 65°C for 2 hours and cooled in a desiccator before weighing for analysis. ...

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.
