Refund & Returns
We want every order to arrive in good condition and match its certificate of analysis. If something is wrong, we make it right. This policy explains our guarantee, when a refund or replacement applies, and how to start a claim.
Last updated July 2026
If your order is lost, held, damaged, or arrives wrong, we reship it or refund you. No dispute needed.

Damaged, wrong, or defective items
Check your order when it arrives. If a vial is broken or leaking, the item is not what you ordered, or the lot does not match its certificate of analysis, contact us within 7 days of delivery. A quick photo of the problem helps us resolve it fast. We will reship the correct item or refund it, whichever you prefer.
In transitLost or stuck shipments
Every parcel ships tracked. If tracking stops updating, a shipment is held, or a package is marked delivered but you do not have it, write to us. We will open a trace with the carrier and, once it is confirmed lost or undeliverable, reship your order or refund it.
Before dispatchCanceling or changing an order
Orders move quickly, often the next business day. If you need to cancel or change an order, or fix an address, contact us as soon as possible and include your order number. If the order has not yet been dispatched, we will cancel it for a full refund or update the details. Once a parcel has shipped, it is on its way and the delivery guarantee above applies instead.
Delivered materialsReturns of delivered research materials
Because these are sealed laboratory research reagents, we cannot accept the return of a correct, undamaged item once it has been delivered. This protects the integrity of every lot for every researcher, since we cannot verify how a product was stored or handled after it left our control. This does not limit your rights under the delivery guarantee above for anything lost, held, damaged, or wrong.
RefundsHow refunds are issued
Approved refunds go back to your original card through our processor, Stripe. Once approved, most refunds appear on your statement within 5 to 10 business days, depending on your bank. We will email you when a refund is issued.
