Ultra-thin wall PCR tubes in strips of 8 and 12 ensure ef cient thermal transfer and maximum yield, yet are strong enough to prevent crushing. Clear tubes provide high clarity for visualizing contents. Unique two-material manufacturing creates the perfect environment for consistent, reliable qPCR performance. Optically-clear caps ensure that the florescence signal is passed through unihibited, creating the perfect environment for consistent and reliable qPCR performance. Strips of flat or dome caps available. Certified free of detectable RNase DNase, DNA, PCR inhibitors, and tested pyrogen-free.
