Instructions
Please send your sample to us “overnight” via traceable means, such as UPS, FedEx or
DHL. Please fill out our sample requisition form and submit with your sample.

Please send the sample to the attention of the Sample Administration Dept. to the
following address:

Sample Administration Dept.
Analytical Research Laboratories
840 Research Parkway, Suite 546
Oklahoma City, OK 73104

Samples will be received at ARL from Monday through Friday (excluding holidays).

If potential degradation due to heat during shipping is possible, we ask that you please
“pack” cold. Please note that ice packs will collect moisture on the surface due to
condensation. This moisture can cause problems with packaging, requisitions forms and
sample labels. It is recommended that the icepack(s) be placed inside a bag that is
sealable such as a zip lock bag.

The following are minimum sample sizes for testing:

Potency
Powders 1 gram

** When submitting drugs for potency testing that are not on our current drug list we ask
that you please call in advance to verify testing capability.
