Field Sampling Log • Chain of Custody
OMMA requires a field sample log when selecting samples for testing.
We've created a field sample log for your use when pulling samples to submit to our Oklahoma laboratories.
For hemp and alternative cannabanoid clients, please select the Hemp Chain of Custody to submit samples.
Client Handbook
Our client handbook contains all the information you need to submit samples to the laboratory.
