New twin.tec 96-well plates are manufactured using technology that combines a polycarbonate frame for mechanical stability and a precise seal that prevents evaporation with polypropylene wells for maximum sample recovery. Ultra-thin wells provide good heat transfer, a secure fit in the thermal block and minimal binding of biological molecules. The plates are certified to be free of human DNA, DNase, RNase and PCR inhibitors, and are available in 384-well and skirted/semi-skirted 96-well formats in 5 vibrant colors.
