The code lives inside it, and nowhere else. There is nothing printed that a person can read off a vial and write down, so there is nothing here to type. Scanning the square opens this page with the answer already in it.
The square sits beside the batch number. A vial can be checked without opening the box it arrived in.
The first reading of a code should be yours. Nobody handles a vial between our facility and the person who receives it, so a count above zero on a first check means something happened along the way.
Reading the same vial again later is normal, and counts normally.
Laboratory research material. Supplied for research use only. Not a drug, not a supplement, and not for administration to humans or animals. A result on this page confirms that a code matches a record we hold. It is not a certificate of analysis, and it is not a warranty of the contents of the vial.
