General description

SampleMatrix® by Biomatrica® is a proprietary core technology to stabilize and protect biological materials at room temperature without degradation. The SampleMatrix technology was designed by combining extremophile biology that enables long-term survival of organisms in extremely dry environments, with synthetic chemistry.

DNAstable® preserves DNA samples at room temperature. Each tube or plate contains DNAstable® as a coating at the bottom of the tube or well, which protects picogram to microgram amounts of RNA. This medium is completely dissolvable and ensures total sample recovery.

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product was Designed for Energy Efficiency. To see how Stanford incorporated Biomatrica Technology and saved substantial amounts of energy, see their published study:

Biomatrica technology enables safe storage of biological material at room temperature.
