Chain of Custody
The Chain of Custody (COC) is used to document information about the sample(s) such as identification/name, time/date of collection, parameter requests and the legal transfer of sample custody. COCs are included with every bottle order we provide. A print version of our Chain of Custody is available below.
If you would like to receive an interactive version of our COC, please email email@example.com.
