ProtectR Tubes Infographic

ProtectR® tubes are the only container closure system engineered to be CO2 resistant. These tubes seal to form an impermeable barrier that prevent costly damage to molecular and cellular solutions when using dry ice. This integral barrier keeps the sample pH stable, preventing acidification. ProtectR® tubes are IATA 95 kPa certified for shipping and withstand high speed centrifugation, autoclaving (121°C) and freezing (-80°C).
