Biological evidence is fragile. The best packaging preserves DNA, prevents contamination, and proves chain of custody. Use breathable paper for damp/drying stains; leak-proof, tamper-evident specimen bags for liquids or transport; and plastic only for fully dried items or sealed primary containers. Seal once, sign/date across the seal, label completely, and store at proper temperature. Purpose-built bags like ADSURE’s meet biohazard and 95 kPa needs.

Chain of custody is crucial in maintaining the integrity and traceability of samples and data, especially in the medical and research fields. This article explores how security bags play a vital role in safeguarding medical samples and research data by ensuring tamper-evident features, secure storage, and accurate tracking, enhancing the overall chain of custody process.
