In principle, it is possible to autoclave our PCR tubes and PCR plates without affecting the material properties as they are made of polypropylene. However, all Multiply PCR tubes and PCR plates produced by Sarstedt are manufactured under cleanroom conditions and are free from DNases/RNases, DNA and PCR inhibitors ('PCR Performance Tested'). This means that the most important parameters for a reliable PCR result are present in advance and our PCR tubes and PCR plates can be used for PCR reactions directly. We therefore recommend that you do not autoclave 'PCR Performance Tested' certified PCR tubes and plates because, contrary to the intention of this step, it results in a risk of contaminating the materials with nucleic acids.
