Your sample

What happens to it.

What if you can't run my sample?
If the compound falls outside our validated scope we tell you before running anything, and you are not charged. For anything unusual, email us first at admin@purilab.org.
Do I get my sample back?
No. Remaining material is destroyed after analysis and the certificate is issued.
Do you ever withhold a result?
No. The certificate reports what the analysis found, whether or not it matches the label claim. Results are never altered or suppressed at a client request.
Can I stay anonymous?
Yes. You choose at checkout whether your certificate is published or kept private. Your name is never printed on a published certificate, and a private certificate is released only to you.

Not covered
