Lot-Matched COA vs a Sample COA | Biscayne Science

Two different documents

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.

What fails when the lot does not match

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.

What Biscayne Science provides

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.
