Multiply PCR Strip of 8 tubes with individually attached flat caps is manufactured from medical grade, transparent polypropylene. The strips feature an anti-contamination shield on the tube rim to protect sample integrity. Each 0.2 ml tube features a thin wall as well as a flat, frosted cap for easy, smear-proof identification. The strip of 8 is compatible with most thermal cycler heating blocks and 8-channel electronic pipettors. All Multiply PCR tubes are certified free of DNase/RNase, human DNA and PCR inhibitors. Single tubes, 4-tube strips and 8-tube strips without caps are also available.
