twin. tec PCR Plates LoBind improve recovery of nucleic acids by reducing their absorption to the tube wall. A combination of special manufacturing technologies and selected polypropylene batches ensures nearly 100% recovery of DNA/RNA molecules-without surface coating to eliminate the risk of sample contamination. twin. tec PCR Plates LoBind are batch-tested and certified by an independent laboratory to be free from DNA, DNase, RNase, and PCR inhibitors.
