Refund Policy
Last updated July 29, 2026
Because catalog materials are intended for in-vitro laboratory research and cannot be re-verified once they leave our facility, all sales are final. This policy explains the narrow circumstances in which we will issue a refund or replacement.
Damaged or defective on arrival
If a vial arrives visibly broken, leaking, or with a compromised seal, contact us within 3 days of delivery with photos of the outer packaging, the affected item, and the shipping label. Verified damage or manufacturing defects will be replaced at no charge or refunded to the original payment method.
Shipping errors
If we ship the wrong item, we will send the correct item and provide a prepaid label to return the incorrect item.
Non-refundable circumstances
- Buyer's remorse or ordered-in-error requests.
- Items opened, compromised, or otherwise altered after delivery.
- Delays caused by the carrier once tracking shows dispatch.
- Refused deliveries or incorrect shipping addresses supplied at checkout.
Order cancellation
Orders can be cancelled before dispatch by contacting us as quickly as possible. Once an order has entered fulfillment we cannot guarantee cancellation.
Chargebacks
Please contact us before initiating a chargeback. We will make a good-faith effort to resolve any legitimate concern.
