Not sure which number is which? The catalogue number is on the vial label and starts with C (for example C4X-105766); the lot number is printed after the words ‘Lot’ or ‘Batch’. If the certificate does not open, email [email protected] with both numbers and we will send the document for that batch.

What the certificate states

Safety data sheets are available for every catalogue item; see Quality and documentation or ask us for the SDS of a specific item.
