  • ProtectR® Dry Ice Tubes
  • Samples of proteins, other biological molecules, and cell cultures are commonly shipped and stored on dry ice, putting them at risk of acidification by up to 2.5 pH units. 
  • In standard centrifuge tubes, CO₂ vapor from dry ice enters the tube headspace and causes a significant drop in the pH of the sample.
  • Even in short term storage conditions, samples may become acidified. This acidification can affect the integrity and reproducibility of samples, and may result in a loss of protein activity. Labcon ProtectR® Tubes prevent CO₂ acidification when storing or shipping samples with Dry Ice.
