Topic / Documentation
Keep peptide stock traceable in the lab: what a vial label should show, what to compare when a new lot arrives, and an inventory log template.
Start with the vial label guide, because the label is the link between a physical vial, its certificate and your records. Note anything the label does not show so it can be added to your log at receipt.
Set up the inventory log template next so every vial has a lot, a location, a receipt date and a link to its certificate. When a new lot of the same peptide arrives, use the lot-change checklist to compare it with the previous lot before it enters use, and record the outcome in the log.
