We want every order from Acuaminos PLLC to arrive exactly as described. If it does not, or you simply no longer need an item, here is how returns, replacements and refunds work.
30-day returns on unused items
You may return any unused item within 30 days of delivery for a full refund of the product price. To qualify, the vial must be unopened with the manufacturer seal intact and in its original packaging. This applies to every product in the catalog, including bacteriostatic water and other lab supplies. No reason is required.
Items that cannot be returned
Because our products are laboratory reagents, we cannot accept returns of opened vials, vials with a broken or missing seal, or products that have been reconstituted, transferred or otherwise used. The specification guarantee below still covers opened vials that do not match their Certificate of Analysis.
Specification guarantee
If a product does not meet the specification stated on its Certificate of Analysis (identity, purity or quantity), contact us within 30 days of delivery and we will replace it or refund the purchase price, your choice, whether or not the vial has been opened. We may ask for the lot number from the vial label and a description of the issue so we can investigate with our lab.
Damaged, missing or incorrect items
Inspect your package on arrival. If anything is damaged, missing or incorrect, email us within 5 days of the delivery scan with your order number and a photo of the package and contents. We reship the affected items at no cost; no return is required unless we ask for it.
How to start a return
- Email admin@acuaminos.com with your order number and the items you want to return (and the reason, if it is a specification or damage claim).
- We reply within one business day with a return authorization and the return address. For returns due to our error or a specification issue we include a prepaid label.
- Pack the unopened items in their original packaging and ship them within 7 days of receiving the authorization. Keep your tracking receipt.
Return shipping
If the return is because of our error (wrong item, damage in transit, specification issue) we pay return shipping. For all other returns the buyer pays return shipping, and the original outbound shipping charge is not refunded.
Refund timing
Refunds go back to the original payment method within 2 business days of our receiving the return or approving a claim. Depending on your bank or card issuer, it can take a further 5 to 10 business days for the credit to appear on your statement. Exchanges and replacements ship within 1 to 2 business days of approval.
Cancellations
Orders can be cancelled for a full refund at any time before they are handed to the carrier. After shipment the return rules above apply.
Exclusions
We cannot refund products that were stored or handled contrary to the storage conditions on the product page, products purchased from anyone other than this website, or any claim that a product did not produce a particular result in an experiment. Our liability for any product is limited to its purchase price.
