  • Guide to the Disruption of Biological Samples - 2012

    Limitations – A significant problem in cryogenic grinding with mortar and pestle is that small samples (e.g., 10-20 mg) can be essentially lost when ground into the surface of the mortar. This makes sample recovery difficult and leads to poor yields. Another major disadvantage of mortars and pestles is that the number of samples that can be processed is low. As the mortar and pestle may be ...
