Refund policy

Because of the experimental nature of our products and the strict requirement to maintain cold-chain integrity, all sales are final. We do not accept returns or exchanges for any reagents, chemical compounds, or research materials.

This policy helps ensure every customer receives materials that have not been compromised by improper handling, temperature fluctuations, or storage conditions outside of our control. Once a product leaves our facility, we cannot guarantee its integrity for resale.

1) Returns & exchanges

  • No returns

  • No exchanges

  • No refunds except as described in Section 3 (Damages / Errors) below

2) Damages, defects, or wrong items (reporting window)

To be eligible for a resolution, you must report issues within 48 hours of delivery.

Issues covered:
