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. Our exclusive molded in elastomeric seal virtually eliminates leaking. And unlike some other seals our ProtectR® and SuperClear® tubes are completely autoclavable. Both the tubes and caps. Our exclusive ProtectR® tubes for shipping on dry ice prevent the sublimation of dry ice into the tubes and into your sample. Most international and domestic carriers now require adherence to the IATA standards for all biological substance shipments. IATA 95 kPa certification ensures containers are leak-resistant under differential pressure conditions such as in air transport. This certification requires containers to prove capable of withstanding, without leakage, an internal pressure producing a pressure differential of not less than 95 kPa (0.95 bar, 13.8 psi). ProtectR® tubes 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 or small volume tubes, samples are at risk of acidifcation. ProtectR® tubes can be used as a secondary shipping tube for multiple small volume tubes.

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. Most international and domestic carriers now require adherence to the IATA standards for all biological substance shipments. IATA 95 kPa certification ensures containers are leak-resistant under differential pressure conditions such as in air transport. This certification requires containers to prove capable of withstanding, without leakage, an internal pressure producing a pressure differential of not less than 95 kPa (0.95 bar, 13.8 psi).
ProtectR® tubes 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 or small volume tubes, samples are at risk of acidifcation. ProtectR® tubes can be used as a secondary shipping tube for multiple small volume tubes. With their airtight, leak-resistant secure seal, ProtectR® tubes provide a protective barrier against CO₂ exposure, safeguarding the sample inside from costly damage. Only ProtectR® tubes 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.
ProtectR® tubes feature our Patented labeling spot that helps to reduce smearing of lab markers at the same time it protects sample labeling from damage during storage or procedures. ProtectR® tubes are available in our exclusive 10 tube IntegraPack® packaging. And like all our sterile products we only use medical grade packaging and sterilize following a validated ISO 11137 medical grade method to an SAL of 10-6.
