Research Material Storage and Labeling Checklist

Good storage practice begins with a complete record. The correct condition is specific to the material, formulation, container, and batch—not a universal temperature copied from a forum.

Research-use boundary: This checklist addresses non-clinical laboratory custody and documentation. Follow the current label, lot documentation, supplier instructions, and your approved standard operating procedure.

At receipt

• Record the material name, labeled quantity, supplier, lot or batch, date received, and receiving person.
• Photograph or document the shipping container, seal, label, and any visible damage before handling.
• Compare the container identifier with the accompanying analytical record.
• Document the package condition and any temperature indicator supplied with the shipment.

Choose conditions from the current record

Storage conditions may depend on formulation, packaging, light sensitivity, moisture sensitivity, and stability data. Do not substitute a generic rule for the current lot documentation. When a label and another record conflict, quarantine the material and resolve the discrepancy before laboratory use.

Use a complete label

A working label should preserve the original identity and lot information and add the date opened or prepared, responsible operator, condition, and any internal sample identifier required by the laboratory. Never rely on color or vial position as the only identifier.

Control access and movement

Maintain a simple chain-of-custody log when material moves between receipt, storage, preparation, analysis, and disposal. Record who moved it, when, from where, to where, and why. Restrict access according to the laboratory procedure.

Respond to an excursion

If a documented condition falls outside the approved range, identify the affected material, preserve the monitoring record, quarantine it, and evaluate it under the applicable procedure. Do not erase or overwrite an excursion. Record the decision and its supporting evidence.

Minimum record

• Identity and lot
• Receipt and open/preparation dates
• Specified condition and actual monitoring record
• Container and seal condition
• Location and chain of custody
• Excursions, investigation, and disposition
