One line per vial: its batch reference, the certificate that covers it, when it arrived, where it is and whether it has been opened. The log flags any vial that cannot be linked to a certificate for its own batch, and any two entries that contradict each other. It is kept in this browser only and exports to a spreadsheet.
The receiving record checks a delivery on the day it arrives. This is the register that outlives the delivery, so that months later, with the packaging gone, the question “which certificate covers this vial?” still has an answer. It is the buyer’s half of the chain described in our batch numbers and traceability note.
Copy each reference exactly as printed, including letters, spaces and dashes. Copy the method and laboratory as the certificate states them. What the terms on a certificate mean.
This tool organises your own records. It makes no assessment of any material, certificate or supplier, gives no usage or dosage guidance, and a complete log is not a statement about what is in a vial. Read our compliance position.
Keep one line per vial with the batch reference printed on the vial, the batch reference on the certificate that covers it, the certificate's test date, method and laboratory, the date received, the storage location and the date it was first opened. The two batch references should match character for character. Any vial whose reference matches no certificate you hold has no analytical record behind it.
In practice none. Both name a quantity of material produced in one run under one set of conditions and characterised as a unit. Suppliers use either term, so a log should copy whichever one is printed, exactly as it is printed.
Enough to answer two questions without the original packaging: which certificate describes this vial, and what has happened to the vial since it arrived. That means both batch references, the certificate's date, method and laboratory as stated on it, the arrival date, the storage location, the opening date and a status such as sealed, opened, held or finished.
Then one reference resolves to two records, which is the same as resolving to none until the supplier explains it. It can be a retest of the same batch, a reissued certificate, or a reference reused across production runs. Ask which certificate was current when your vial was dispatched, and keep both.
The batch comparison is the same one the receiving record uses, so the two tools agree on whether two references match.
