Lot traceability links each container to the lot it came from, and the lot to its certificate of analysis and its history. It lets a laboratory record exactly which material was used in an experiment and match it to the test results for that lot.
The shop's own lot-tracking system shows, on each product page, the lot currently on sale with its lot ID, purity and verified quantity.
