What to check with any supplier

The format it arrives in
Whether a compound comes as a pre-mixed solution or as powder changes what has to happen before it can be used in the lab. Our catalogue
The paperwork for your batch
Ask whether a Certificate of Analysis is tied to the batch you receive, and whether you can see examples before you order. Our COA library
Dispatch and packing
Check where orders ship from, the daily cut-off, and how parcels are packed to stay cold in transit. Our shipping policy
Returns and damaged parcels
Read the returns window and what happens if a parcel arrives damaged, before you need to. Our returns policy
A way to reach a person
A support page and an email address that someone answers matter more than any badge. Contact support
