Common questions
What does research use only mean?
Every product here is a laboratory reference standard supplied for in-vitro research. It is not a drug, food, supplement, cosmetic or medical device, and it is not for human or veterinary use.
Does every product come with a certificate?
Yes. Every product listed carries a lot-specific certificate of analysis, and the PDF is downloadable from the COA library before you order.
Who is allowed to order?
Orders are accepted from qualified researchers and research entities only. You confirm this at the gate and again at checkout.
Can I get the certificate for the exact lot I receive?
The certificate published against each product is the one for the lot currently in stock. If you need a certificate for a lot you already hold, contact us with the lot number.
How are orders shipped?
Orders ship fast and tracked. You receive the tracking number by email as soon as the label is created.
Do you offer wholesale pricing?
