For use with rDNA and viscous proteins, these nonstick, graduated, polypropylene tubes may be used between –80 and 122 °C (–122 and 251.6 °F).

They feature flat caps and frosted areas on the sides for easy labeling. Leakproof snap caps may be penetrated by a syringe. Easy-to-open caps will not pop open during autoclaving. The 0.5 mL tubes fit many thermal cyclers. All tubes are nonsterile. RNase- and DNase-free.
