Capture clean data and preserve provenance from day one. This segment sets up sample IDs, barcodes or QR codes, chain-of-custody forms, freezer maps and tidy data templates so every tube, plate and file can be traced from source to analysis.

• Sample ID schema with barcode or QR implementation across batches
• Chain-of-custody forms for handoffs, timestamps and transport conditions
• Freezer map and storage location registry for samples and controls
• Template pack for sample logs, checklists, labels and basic registers
• Deviation flags and simple reconciliation workflow for missing or swapped items
• Data handoff to analysis with tidy schema mapping for spreadsheets or LIMS
