Research use only labeling: what the statement means and where it has to appear

Research use only, or RUO, is a statement about who a product is for: laboratory research, not people or animals. It only carries weight when the rest of the store agrees with it. This guide covers where the statement should appear, a template to start from, and the common ways stores contradict their own label. It is general information, not legal advice.

Where the statement belongs

PlaceWhat to show
Vial labelFor research use only. Not for human or veterinary use. Plus the lot number.
Product pageThe same statement, near the price and add to cart, not only in the footer
CheckoutA confirmation box the buyer ticks, stating the purchase is for research use and that they are of legal age
Order emails and invoicesA one-line reminder of research use only
Terms of saleThe full statement, with the buyer's agreement and your right to refuse orders

A disclaimer template to adapt

Adapt this with your lawyer to your own business and jurisdiction:

All products sold by [Company] are intended for laboratory research use only. They are not for human or veterinary use. By placing an order you confirm that you are at least 21 years old, that you are purchasing for lawful research purposes, and that you will handle and store products according to laboratory standards. [Company] may refuse or cancel any order.

Mistakes that undercut the label

  • Product descriptions or FAQs that explain how a person would use the product.
  • Social posts, reviews or influencer content that contradict the label.
  • Bundles or product names built around a personal goal.
  • A disclaimer in tiny footer text while the rest of the page reads like consumer retail.
  • Different wording on the label, the page and the invoice.

Consistency is the whole point. The label, the page, the checkout and the email should all say the same thing.

How Purity handles it

Every Purity store shows the research use only line on product pages, and every photographic vial carries it on the label with the lot number. Checkout asks the buyer to confirm research use, and the wording check runs on pages, emails and texts. Your terms, shipping and refund policies are linked from the store and from order emails.

Common questions

Is research use only a legal status?
It is a statement of intended use. Its weight depends on whether the way you market and sell the product matches it.
Does the statement need to be on the vial?
Yes. The label is the part the buyer keeps, and reviewers check it.
