Use Axygen® Thin-Wall PCR Tubes for polymerase chain reaction (PCR) and real-time PCR (qPCR) experiments, reverse transcription applications, and more. The ultra-thin walls allow precise and consistent thermal transfer in a wide variety of thermocyclers. These RNase/DNase-free, non-pyrogenic, non-sterile tubes are available in flat or domed cap designs. The flat cap design ensures a tight seal, reduces sample evaporation, and allows for easy labeling of samples, while the domed caps increase the efficiency of heat transfer.
