ProtectR® Dry Ice Storage Tubes

Key Features

  • Tested and certified to the IATA 95kPa standard
  • Patented writing surface prevents smeared ink and protects your notes
  • Flat caps with integral molding in two material seal are virtually leak proof
  • Tube are printed with three colors that highlight important features of the tubes.
  • USP Class medical grade resins and packaging. ProtectR tubes are for all lab uses.

Full Protection of Your Samples
 

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.

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, 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(s) 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.

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 feature our Patented ViewPoint 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 method.

ViewPoint Thermochromatic Centrifuge Tubes

  • Real Time Temperature: Patent Pending real time temperature signaling.
  • UV Protection: Prevents damage to biomolecules from UV.
  • Temperature Control: Maintain desired temperature throughout experimentation.
  • Certified Safe: Tested and certified safe for use in Cell Culture and other critical work.
  • Wide Range of Options: Available in sterile and non sterile packaging with three tube styles.
  • Medical Grade: USP Class medical grade resins and packaging. Safe for all lab uses.

Real-Time Temperature Signaling
ViewPoint tubes transition from clear to blue when exposed to cold temperatures. This multi-step and reversible thermochromic transition offers real-time temperature signaling to indicate fluctuations above and below 4°C. At 5° C and above ViewPoint tubes are clear and transparent. At 4°C ViewPoint tubes transition to light blue and become slightly opaque. At 0°C ViewPoint tubes reach their full progressive transition to dark blue, are completely opaque, and provide protection from Ultraviolet (UV) light.

Patents Pending.

Optimize Incubation Time On Ice
A large number of protocols require chilled cells and/or chilled solvents. In these protocols samples and solutions are chilled for 30 minutes, 3 hours, or overnight. ViewPoint signals that a sample is chilled to 0 - 4°C. Efficient chilling reduces incubation time, saving researchers time in a busy workflow.

Real-Time Temperature Signaling Protects Samples
It is critical to reduce the formation of ice crystals when working with aqueous samples. Ice crystals begin to form at 0 – 4°C and damage cells. ViewPoint tubes begin transitioning from clear to light blue at 4°C with full dark blue signaling at 0°C. Real-time temperature signaling alerts the researcher to potentially harmful ice crystal formation and enables the maintenance of the desired temperature throughout experimentation.

Protection from Ultraviolet Radiation
When fully dark blue (0°C) ViewPoint tubes provide added protection from Ultraviolet (UV) light. Unlike other tinted products, ViewPoint tubes become opaque at 0°C and provide protection from UV, eliminating the need for wrapping tubes in aluminum foil to shield sensitive samples from light radiation. Without a bulky aluminum foil wrap, ViewPoint tubes fit perfectly into racks and can be clearly labeled on the frosted writing surface.

ViewPoint tubes are available in our exclusive IntegraPack® 10 tube packs, reusable polypropylene racks, and non-sterile bulk bags (1.5 mL) All our sterile products use medical grade packaging and are radiation sterilized following a validated ISO 11137 method.

ViewPoint tubes are patent pending. The three-color tube labeling graphics are copyright, trademark, and trade dress of Labcon North America.
