Three checks before opening a research catalogue

1. A batch number is the starting point

A product name is not enough to connect a document to a specific material. Match the lot or batch number on the catalogue page to the number on the report. If either is absent, record that the connection could not be checked.

2. A percentage needs a method and scope

A reported percentage has meaning only alongside the method, result and acceptance limit it describes. It should not be stretched into a claim about properties that were not listed, or about a different batch.

3. Selected-lot testing is not a universal claim

A merchant may provide independent results for selected lots. That can be useful documentation for those lots, but it does not automatically describe every item in a catalogue. Check the report associated with the material you are reviewing.

Keep the categories separate

A batch report describes analytical documentation. It does not establish a medicine authorisation, clinical outcome or suitability for human use. Research materials and approved medicines belong to different categories.
