Why lot traceability matters in research supply

Traceability connects the vial on the bench to the analytical record behind it.

ALORA Editorial · May 30, 2026

Two vials with the same compound name are not necessarily the same material. They can come from different production runs, tested at different times, with different results. Lot traceability is what lets you tell them apart.

One number, one batch

Every ALORA vial is printed with a lot number starting with ALR-. All vials from one production run share that number, and that number has one record: its test date, laboratory, methods and results.

From the label to the record

The lot number on the label is also encoded in a QR code. Scanning it — or typing the number into the COA library — opens that lot’s page, so the vial on your bench connects directly to the documentation behind it.

Why it matters for research

Reproducible work depends on knowing exactly what material was used. Recording the lot number alongside your experiment means you can always return to the report for that batch, compare results across lots, and flag a specific batch if something looks off.

When lots change

When a new lot replaces an older one, the older record stays in the library as an archived lot rather than disappearing, and each record links to the lot it replaced or was replaced by.
