Frequently asked

What documentation is supplied with this lot?

A certificate of analysis (COA) is issued for the lot you receive. It records the catalogue number RS-Z401KJ2 and the batch number, the tests performed, the specification applied and the result obtained. A safety data sheet is supplied with the shipment.

Is the assigned value given on an “as is” basis?

Content and purity are stated per lot on the certificate of analysis, on an “as is” basis unless the certificate says otherwise. The analytical basis for the assigned value is stated on the certificate.
