Returns policy

Sealed materials
Because these are research chemicals whose chain of custody cannot be re-established once they leave our control, opened or unsealed items cannot be returned.
Damaged or incorrect shipments
Report a damaged, incorrect, or missing item within seven days of delivery with the order number, lot number, and photographs. We will replace or refund confirmed errors.
Documentation discrepancies
If a supplied lot does not match its published batch record, stop using the material and contact us. We will investigate and, where warranted, replace, refund, and update or withdraw the affected record.
