Laboratory documentation guide

Research compound storage and documentation

Good records separate what the supplier states from what the receiving laboratory actually observed and controlled.

Record receipt before storage

Document the received date, container condition, label, batch identifier, and any temperature indicator or shipping exception. Preserve the original product documentation.

Follow the applicable source

Storage conditions should come from the product label, matched batch document, safety data, or another authorized source. Do not infer a condition from a different product or lot.

Maintain a handling log

• Storage location and monitored condition
• Date and time removed or returned
• Container openings and transfers
• Observed damage, contamination, or excursion
• Person responsible for each material event

Keep claims bounded

A storage log documents custody and conditions; it does not replace analytical testing or prove that a material retained every attribute over time.
