Delivery protection
Delivery protection is included on every order at no cost. If a shipment is lost in transit or arrives damaged, we replace it.
Packaging
Plain outer packaging with nothing on the outside identifying the contents. The return address is a fulfillment address. Temperature-sensitive material ships with insulated packaging and coolant where required.
On arrival
Inspect the shipment. Refrigerate temperature-sensitive material immediately. If the package arrives damaged, if the coolant is fully spent, or if there is any sign the cold chain was broken, do not use the contents — contact us within 72 hours and we will replace the order.
Returns
These are temperature-sensitive research materials. For safety and traceability reasons, we cannot accept returns of opened, used, or temperature-exposed items.
We will replace or refund, at our option, where:
- the order arrived damaged or with a compromised cold chain (report within 72 hours)
- you received the wrong item
- an item was defective on arrival
Unopened supplies (syringes, swabs, bacteriostatic water) may be returned within 30 days in original condition.
Failed or refused deliveries
If a delivery fails because of an incorrect address you supplied, or is refused, we cannot resend material that has been out of temperature control. Please check your address before confirming.
