Our Guarantee

If you send us data showing that our enzymes do not work for you, and you send back the unused remainder of a tube of enzyme, we will tear up the invoice. More than likely, if you send us a description of your experiment, we will have advice to make your PCR work.

Also, if you have a fire or theft, or accidentally step on a tube, let us know, and we will send a replacement if you pay the shipping.
