Tubes (white) and Ultra Clear Caps, strips of 8

White plates and tubes reflect significantly more signal back to the qPCR instrument's detector than traditional clear plates. The improved signal reflection ensures that even the lowest levels of fluorescence are detected. White well walls also prevent signal from passing through to the cycler block where it can be inconsistently reflected or absorbed. This keeps variations in the cycler block from affecting qPCR data. Using Thermo Scientific white PCR plastics increases sensitivity and reduces variability within the qPCR assay.

They are not certified endotoxin-free. However, their entire production process, from molding to final packaging, is carried out in a Class 100,000 clean room under ISO 9001 guidelines. All Thermo Scientific PCR plastics are certified free from RNase, DNase and human DNA.

Thermo Scientific Abgene plastics are not typically sterilized as their entire production process, from molding to final packaging, is carried out in a Class 100,000 clean room under ISO 9001 guidelines. All Thermo Scientific PCR plastics are certified free from RNase, DNase and human DNA. In contrast, during typical non-clean room production, plastics are exposed to many contaminants including dust, bacterial cells, and DNA. The plastics are then sterilized to kill bacteria and inactivate RNases and DNases, but sterilization does not remove dust or DNA contamination. The dust particles left behind can inhibit PCR, and the damaged DNA fragments can still act as templates, leading to non-specific amplification.
