Who can purchase from this catalog?
Products are sold for laboratory and in vitro research only. Purchasers must be qualified researchers or institutions operating under appropriate oversight. We do not sell for human or veterinary administration.
Why do I need to sign in to see pricing?
Authenticated access helps us maintain catalog integrity, provide batch-specific COA downloads, and support researchers with order history and documentation.
How do I access a certificate of analysis?
After signing in, COA documents are available from product pages and your order history for the specific batch shipped. Visit our Certificates page for an overview of our testing standards.
How are orders shipped?
Orders are processed quickly and shipped with reliability in mind — what you order goes out on time and arrives as expected, with cold-chain handling when required. Free shipping applies on orders over $200.
What is your return policy?
We stand behind every order with a 100% money-back guarantee when something isn’t right. If we ship a damaged or incorrect product or otherwise fail to deliver what you ordered, we’ll refund or replace it. Opened or used research chemicals cannot be returned to inventory — see our Returns policy for details.
Do you offer bulk or institutional pricing?
