Research / Lot-matched versus a sample COA
Documentation comparison
Same kind of PDF can answer two different questions. The useful one is whether the file matches your vial.
A sample or representative certificate may describe a lot other than the one you received. A lot-matched certificate uses the lot number on your label. Biscayne Science provides lot-matched Certificates of Analysis on request, from accredited third-party batch testing.
This page compares documentation practices. It does not rank unnamed suppliers, and it does not make a claim about experimental outcomes.
Identity, purity, and endotoxin are properties of a batch. A file from a different batch cannot confirm the vial on the bench. The questions a lab buyer can actually check are printed below.
Biscayne Science holds a hard purity floor of at least 99% by HPLC on every compound, with mass-spectrometry identity confirmation. Endotoxin is screened to under 0.25 EU/mg by accredited LAL assay, and each batch is tested for sterility. Testing is done by an accredited third-party lab. A lot-matched Certificate of Analysis is available on request and is tied to the lot printed on the vial, not a representative sample from another batch.
A certificate reports those research results for that lot. It is not a representation that a material is safe or suitable for any use in humans or animals. The request path is the Certificate of Analysis page.
A certificate offered as an example or as representative of a product, which may not be the lot you received.
A lot-matched Certificate of Analysis on request, for the lot on the vial, covering the tests stated on this site.
