Refund and Returns Policy

Overview

Our refund and returns policy lasts 30 days. If 30 days have passed since your purchase, we can’t offer you a full refund or exchange.

To be eligible for a return, your item must be unused, unopened and in the same condition that you received it. It must also be in the original packaging with any seals intact.

Because they are sterile laboratory supplies, opened or unsealed vials of bacteriostatic water, buffered water and diluents cannot be returned. We also do not accept hazardous materials or flammable liquids.

To complete your return, we require a receipt or proof of purchase. Please do not send your purchase back to the manufacturer.

There are certain situations where only partial refunds are granted:

Any item not in its original condition, or damaged or missing parts for reasons not due to our error.
Any item that is returned more than 30 days after delivery.

Refunds

Once your return is received and inspected, we will email you to notify you that we have received your returned item. We will also notify you of the approval or rejection of your refund.

If you are approved, your refund will be processed and sent to your original method of payment within a certain number of days.

Late or missing refunds

If you haven’t received a refund yet, first check your bank account again. Then contact your bank or payment provider; there is often some processing time before a refund is posted.

If you’ve done all of this and you still have not received your refund, please contact us at info@stack-science.com.

Sale items

Only regular-priced items may be refunded. Sale items cannot be refunded.

Exchanges

We only replace items if they are defective or damaged on arrival. If you need to exchange an item for the same item, email us at info@stack-science.com with your order number and a photo of the item, and we will send you return instructions.

Shipping Returns

Once your return is approved, we will email you the address to send it to.

You will be responsible for paying for your own shipping costs for returning your item. Shipping costs are non-refundable. If you receive a refund, the cost of return shipping will be deducted from your refund.

If you are returning more expensive items, you may consider using a trackable shipping service or purchasing shipping insurance. We don’t guarantee that we will receive your returned item.
