Does every Sable vial have a lot number?

Yes. Every vial carries a printed lot number, and every lot has its own CoA.

How it works at Sable

Every vial carries a lot number. The certificate of analysis for that lot is listed in the CoA library.

Lot number: A lot number, or batch number, is an identifier assigned to a particular quantity of material produced under uniform conditions. It links a product to its manufacturing and quality-control records, including the certificate of analysis, and allows a researcher to trace results back to the specific material used.
Glass vial: A glass vial is a small container used to store laboratory materials. Peptides are commonly supplied in borosilicate glass vials sealed with rubber stoppers and aluminium crimp caps.
