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. ProtectRtubes are the ideal vessel for primary and secondary sample containment. Samples are shipped on dry ice in a variety of volumes. When shipped in standard, small volume tubes, samples are at risk of acidifcation. ProtectRtubes can be used as a secondary shipping tube for multiple small volume tubes. With their airtight, leak-resistant secure seal, ProtectRtubes provide a protective barrier against CO2 exposure, safeguarding the sample(s) inside from costly damage.
Only ProtectRtubes ensure consistent sample integrity and protein activity across experiments. Even if samples are delayed during shipping, they will not become compromised, saving time and money. Most international and domestic carriers now require adherenc(more…)
