Wildlife forensics and conservation research require precise sample preparation techniques for analyzing biological materials such as pangolin scales, elephant teeth and skulls, and tiger skin and hair. These biological specimens are essential for forensic investigations, species identification, and conservation initiatives because they provide genetic, isotopic, and structural information that can help trace the origin of animals, determine cause of death, and identify victims or perpetrators in wildlife trafficking cases.
Due to the hardness and thermal sensitivity of these materials, traditional grinding methods often result in sample degradation, DNA shearing, or inconsistent particle sizes. Cryogenic grinding, using a Freezer/Mill®, offers a reliable and reproducible method for pulverizing these challenging samples while preserving their molecular integrity.
This method enhances DNA extraction, stable isotope analysis, and forensic identification, all of which are critical for wildlife conservation, enforcement of anti-trafficking laws, and improving analytical precision. Unlike conventional grinding, cryogenic milling prevents heat-induced degradation, ensures sample purity, and yields uniform particle sizes, making it the preferred approach for processing tough biological materials.
