Safe and Efficient Cryogenic Sample Preparation at -196°C

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.
