Batch certificates of analysis
Every documented lot published on this site, with its certificate of analysis data: lot number, appearance, HPLC purity, ESI-MS identity confirmation, analysed quantity, sterility and heavy metals.
How to read this table
Each row is one product and one lot. The lot number in the first column is the identifier printed on the certificate issued for that material, and it is the same lot number shown on the product record. Use it to match the document you receive to the record published here.
Purity is the HPLC result for that lot, measured with UV-VIS detection at 214 nm against a specification of not less than 99.0%. Identity confirmation is the measured mass reported by ESI-MS. Analysed quantity is the fill determined by quantitative HPLC, within a 10% tolerance of the labelled target.
Which products are covered, and which are not
Eleven of the fourteen products in this catalogue appear in the table below. Liraglutide, Cagrisema and SLU-PP-322 do not, because no certificate for them is held in this set. Their product records state that no certificate is published, which is the honest position rather than an omission.
Testing laboratory and methods
The certificates were issued by Lens Bio Lab, an independent analytical laboratory, with a sample receipt date of Sep 21, 2026 and a test date of Sep 26, 2026 for the current lot records. Appearance, sterility by USP <71> and heavy-metal screening by ICP-MS are reported on the same certificate.
Where a certificate does not carry a field — a CAS number, molecular formula or amino-acid sequence, for example — the corresponding product record states that it is not published, rather than supplying an estimate.
Requesting a certificate for a specific lot
The certificates summarised here are the records held for the lots currently published. If you need the document itself for a specific lot, or for a lot not listed here, request it through the research desk on WhatsApp and state the product name and the lot number.
Ordering remains inquiry only. No price is published anywhere on this site.
