When a result cannot be repeated, the first question is usually about the reagent. Good lot traceability answers it in minutes instead of weeks.
What to record on arrival
- Supplier, product name and catalogue number
- Lot number and CoA reference
- Date received and condition of packaging
- Storage location
What to record on use
- Reconstitution date, diluent and volume
- Calculated concentration
- Aliquot labels and freezer position
- Experiments that used each aliquot
Digital vs paper
Electronic lab notebooks and inventory systems make searching easy, but even a simple shared spreadsheet beats memory. Link each dataset to the reagent lot.
