Submission FAQ
Common questions before sending samples to the laboratory.
What information should I include?
Provide the sample name, batch or lot reference, requested analyses, expected specifications, and any relevant background documents such as an existing COA or analytical summary.
Can I request multiple tests at once?
Yes. You can request a single method or a broader package such as purity, identity, endotoxin, heavy metals, sterility, or a custom analytical panel.
What if my sample has special handling needs?
Note any storage conditions, stability concerns, hazardous handling requirements, or chain-of-custody expectations in your request so intake can be reviewed appropriately.
Do you support COA verification?
Yes. If you want independent review of an existing certificate, include the COA and any supporting analytical data when available, or visit the COA Verification page.
What happens after submission?
After review, the laboratory can assess scope, confirm suitable methods, and advise next steps for sample acceptance, documentation, and testing workflow.
Can I send supporting documents?
Yes. Supporting files such as COAs, specifications, chain-of-custody records, and prior analytical data are helpful for accurate review and planning.
