Use of innovative sample dryer for effective sample drying in forensic investigations: An experimental study.

Back Ground: The sample collection and preservation before transportation to a Forensic Science Laboratory in a medicolegal case in India is a crucial step in establishing a link between accused, victim, crime scene and the weapon. This paper discusses pioneering advancement in health technology-a state-of-the-art sample dryer developed to preserve biological samples during Forensic investigations. This unique design has been officially registered with the design office in India as a copy right.

Aims And Objectives: The primary goal of the sample dryer is to augment the preservation of biological evidence by removing moisture content through air drying before packaging, sealing and its transportation to a Forensic Science Laboratory.

Material And Methods: The process of air drying of biological samples by variety of experiments conducted in sample's dryer designed for the purpose which employs a range of air movement techniques including horizontal, vertical, and circular laminar flows to swiftly extract moisture from the samples. The drying duration for each experimental sample was documented upon manual confirmation of complete drying.

Results: The results were extraordinary, showcasing that the sample's dryer reduced the drying time drastically by up to 27 times lesser in comparison to conventional methods for identical samples. The diverse airflow patterns generated by the sample dryer unequivocally demonstrated it's utility in achieving superior sample preservation through efficient air drying.

Conclusion: Given the exceptional outcomes observed in the experimental phase, the authors strongly advocate for the widespread adoption of this innovative sample's dryer equipment to ensure effective air drying of biological samples and their efficient sample preservation to enable successful forensic analysis as expected.
