BSD punch instruments are used globally as a trusted tool for many forensic applications, including databasing, casework, paternity, ancestry, post-mortem, toxicology, and human identification.
Sample collection and processing are important steps in the legal investigation process. Collection of different samples such as dried blood, saliva buccal, urine, faeces or tissue sample including hair follicles on sample collection cards are proven methods for use in forensic biology.
The objective of the BSD semi-automatic punching system is to ensure uniform sample aliquots are taken from sites of interest, while minimizing potential contamination and maintaining traceability. With punching being a physical process, the design of the punch head and features for cleaning are critical factors of puncher design.
