Research materials, with the certificate attached.
We publish a purity figure only when we can show the certificate of analysis alongside it, with the batch number and the date the analysis was carried out. Where a product has no certificate, we quote no figure. That is deliberate: a number without a document is not a fact.
Analyses are carried out by an external laboratory, not by us. The certificate states the method used, the purity determined, the batch number and the date. You can read the document yourself before ordering.
All products are supplied solely for scientific research and laboratory use. They are not intended for human or animal consumption, diagnostic use or therapeutic application. It is the buyer's responsibility to establish what is permitted in their jurisdiction.
