All products →What does "research use only" mean?
Every product is a laboratory reference standard supplied solely for in-vitro research — not for human or veterinary use, and not a drug, food, supplement, cosmetic, or medical device.
Is a Certificate of Analysis included?
Yes — every tested lot is matched to a third-party COA covering identity and purity. Browse and download them in the COA Library, before or after purchase.
How do I pay?
Choose a method at checkout, send the total directly, then email a screenshot as proof. Your order is reserved and ships once payment is confirmed — no card is charged on the site.
Who can purchase?
You must confirm you are at least 21 and a qualified researcher (or authorized to buy for a research institution). This is recorded with every order.
Reference standards,
documented to the lot.
Infus Labs supplies lyophilized research reference standards for laboratory research use only — every batch independently tested, every lot on the record.
