New flex-free strips are reinforced to resist bending while handling. Individually attached flat caps are optically clear for use in real time procedures, are easy to handle, and help avoid cross-contamination. Polypropylene thin wall tubes provide rapid, even heat transfer for reliable amplifications. Low profile tubes help reduce condensation when using very small volumes. Manufactured in clean room conditions and certified free of detectable levels of DNase, RNase, DNA, and PCR inhibitors. Tested pyrogen free. Tube portion is available in either natural or white. Each pack contains 10 individual bags of 12 strips for a total of 120 strips (960 tubes and caps).
