IIIVerify
Check a lot before you use it.
Every vial carries a lot number. Enter it to retrieve the independent certificate for that exact lot — purity, test date, and the laboratory that ran the assay. No account required.
Example lot: DNL-2026-0417
IVThe standard
Purity claims are worth nothing without the paperwork.
Anyone can print a number on a label. What matters is whether you can check it — against a named laboratory, a dated assay, and the specific lot in your hand.
Common practice
- A purity figure with no assay behind it
- One certificate reused across every lot
- Testing laboratory unnamed
- No way to match a vial to its documentation
Denuo
- Independent HPLC assay on each lot
- A distinct certificate per lot, published openly
- Testing laboratory named on every certificate
- Lot number on the vial matches the certificate online
VWhy Denuo
Built for the bench.
Independent assay
Purity determined by HPLC at a third-party laboratory, not in-house. The result is published on the product page before you buy.
Lot-level certificates
Every lot carries its own certificate of analysis with test date, laboratory, and result. Older lots stay published rather than being replaced.
Full specifications
CAS number, sequence, molecular formula, molecular weight, physical form, storage, and solubility listed on every item.
Controlled handling
Lyophilized material stored and dispatched under conditions appropriate to the compound, with tracked delivery.
Traceable labelling
The lot number printed on the vial resolves to the certificate for that exact lot. No ambiguity about what you received.
Research supply, plainly stated
We supply reference materials for in-vitro laboratory work. We do not publish protocols, dosing, or usage guidance of any kind.
VIOrdering
Ordering, in three steps.
-
01
Review the specifications
Each product page lists full chemical specifications alongside the certificate of analysis for every lot we have supplied.
-
02
Place your order
Confirm the research-use terms at checkout. Orders are accepted from qualified researchers and institutions.
-
03
Receive and verify
Your vial arrives labeled with its lot number. Match it against the published certificate to confirm what you received.
VIICommon questions
Before you order.
Are these products for human use?
No. Everything we supply is a chemical reference material intended for in-vitro laboratory research. Our products are not drugs, foods, cosmetics, or medical devices, and are not intended for human or veterinary administration in any form. We do not provide dosing or usage guidance and cannot answer questions of that kind.
How is purity determined?
Each lot is assayed by an independent third-party laboratory using HPLC. The result, the test date, and the laboratory are published on the certificate of analysis for that lot.
What documentation comes with an order?
Each vial is labeled with its lot number, which corresponds to a certificate of analysis published on the relevant product page. Certificates remain available after a lot sells out.
Who can order?
Orders are accepted from qualified researchers, laboratories, and institutions. Purchasers are responsible for handling, storage, and disposal in line with applicable law and their own institutional requirements.
How is material stored and shipped?
In-stock orders are dispatched within one business day of payment clearing; orders placed at a weekend or on a public holiday go out the next business day. Lyophilized material is stored under conditions appropriate to the compound and dispatched with tracking. Storage requirements for each item are listed in its specifications.
Every lot documented. Every certificate public.
Browse the catalog and read the certificates before you order anything.
