Made of pure, virgin PP. PCR tubes 0.2 and 0.5 ml with attached caps are compatible with leading thermal cyclers with heated lids. Unique cap design closes and opens easily without tools, yet ensures a tight fit to reduce sample evaporation. The various colours of the PCR tubes allow fast sample classification. Extra-thin, uniform wall to provide the optimal thermal transfer and short cycle times. Free from RNase-, DNase- and DNA. Autoclavable (121 °C). Made of pure, virgin PP.
