A lot number connects a study material to its particular evidence.
A result belongs to a sample
A paper, chromatogram or certificate describes the material that was actually tested. Without a reliable link from that sample to the container used in a study, a reader cannot know whether the reported analysis applies. Record the lot identifier and keep the matching label and documents with the research record.
Reproducibility across supplies
The published obestatin comparison found meaningful differences among commercial samples. Separate source and lot details therefore matter when another laboratory tries to reproduce a result. Batch traceability does not guarantee quality by itself, but it makes discrepancies investigable and allows relevant test results to be checked.
Retain the exact lot, supplier specification and relevant test documents for each material used in an experiment.
