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-F029226 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.
How should this material be stored?
Store as stated: Refer to the certificate of analysis (COA) supplied with each lot. Re-test before use beyond the retest date printed on the certificate.
Do you supply pack sizes other than those listed?
Pack sizes are confirmed with the quotation. Quantities beyond the standard pack sizes can be quoted — send the quantity you need with your enquiry.
