Gate first, supply second
We built the review step before the storefront. Nothing about our materials — identity, price, or availability — is visible until an application has been approved by a person on our compliance team.
About
A procurement network built around review, not reach
Purity Partners USA exists to make institutional laboratory supply boring, documented, and defensible. We are a membership body with a supply function attached — not a store with a gate bolted on.
Operating principles
Institutions, not individuals
Members are universities, contract research organizations, commercial and public-health laboratories, and industrial R&D groups. We do not open accounts for private individuals.
Traceability as a default
Every released lot is assigned a lot code and a certificate of analysis. Approved members can trace any received unit back to its test record through certificate access links in the portal.
Restraint in what we publish
We publish no compound names, structures, synonyms, or images of labelled material. Public pages describe process and governance only.
How we got here

Who reviews applications
Applications are read by our membership and compliance desk, which includes analytical chemists and a regulatory reviewer. Reviewers check the institution, the plausibility of the stated in-vitro use, the shipping destination, and whether the request falls inside what we are willing to supply. Reviewers may request documentation, may approve with conditions, and may decline without giving a reason.
