Sarstedt has expanded its line of Multiply®-µStrip PCR tubes to include a white option for qPCR. The reflective white wells maximize fluorescent signal intensity, minimize cross-talk, and enable volume reduction of expensive reagents without compromising sensitivity or stability. The thin-walled strips of eight 0.2 ml white PCR tubes are compatible with most popular thermocycler heating blocks and 8-channel pipettes. High-purity tube strips are batch certified by an independent laboratory to be free of DNase, RNase, human and bacterial DNA, and PCR inhibitors. Flat, optically transparent lid chains are available separately.
