Give your cryogenic storage tubes and vials extra protection when needed with Thermo Scientific™ Storage Tube Protection accessories. For example, safeguard your samples when storing in liquid or vapor phase nitrogen, or when shipping samples. These cryogenic storage accessories, such as tube wraps, sleeves and mini-boxes, have safe handling in mind.

If you want to submerge your cryotubes in the liquid phase of nitrogen, seal them first inside Nunc™ Cryoflex™ tubing to prevent liquid nitrogen from infiltrating the tube. Cryoflex™ tubing can used to crimp and heat shrink an impenetrable safety skin around the tube prior to submersion.
Nalgene™ CryoSleeves™ slide over any Nunc or Nalgene Cryocane and prevent tubes from falling out of the cryocane and into the bottom of the liquid nitrogen dewar. Nalgene™ CryoSleeves™ do not prevent infiltration of liquid nitrogen. Cryogenic tubes mounted in the cane must first be sealed inside Cryoflex™ tubing prior to applying the CryoSleeve™ if liquid phase submersion is required.
Nunc CryoTube™ miniboxes with a friction-fit lid are ideal for storing small quantities of samples and shipping.Made with durable, high-impact, polystyrene to protect samples.

Frequently asked questions (FAQs)

Will the heat required to properly seal Nunc CryoFlex Tube Wrap adversely affect my cells?

Nunc Biobanking and Cell Culture Cryogenic Tubes are normally placed in a 4 degrees C ice bath during cell inoculation in the cryogenic tube. The heat required to shrink the polyethylene Nunc CryoFlex Tube Wrap will not raise the internal temperature enough to damage the cells. At this stage, cryoprotective agents are added.

What protocol should I follow for thawing cells, if my Nunc Biobanking and Cell Culture Cryogenic Tubes were previously immersed in liquid nitrogen without Nunc CryoFlex Tube Wrap?

We recommend the following protocol for thawing cells immersed in liquid nitrogen without Nunc CryoFlex Tube Wrap:
- Wear appropriate protective clothing including gloves, face guard, etc., during all transfer processes.
- The Nunc Biobanking and Cell Culture Cryogenic Tubes should be stored at least 24 hr in the gas phase of the liquid nitrogen freezer. This should allow trapped liquid nitrogen to evaporate and escape slowly, thereby reducing the possible pressure in the cryogenic tube.
- After at least 24 hr storage in the gas phase, the cryogenic tube may be put into a water bath and covered with a towel.
- After thawing, the contents of the cryogenic tube can be transferred.

Can I immerse Nunc Biobanking and Cell Culture Cryogenic Tubes in liquid nitrogen (liquid phase) for storage?

Of the Nunc Biobanking and Cell Culture Cryogenic Tubes, we recommend the internally threaded design, incorporating a silicon gasket, for liquid nitrogen immersion. At ultra low temperatures, any sealing material becomes inflexible. A theoretical risk of leakage is present when any mechanical closure is used. To facilitate leakproof storage, mechanically closed containers must be hermetically sealed in a protective envelope.

The Nunc cryo products includes Nunc CryoFlex Tube Wrap, a heat sealable polyethylene tubing designed for cryogenic tube encasement. The use of cryogenic tubes for freezing in liquid nitrogen (liquid phase) storage without CryoFlex tubing poses a safety hazard.
WARNING: Do not use Nunc Biobanking and Cell Culture Cryogenic Tubes in liquid phase of liquid nitrogen unless correctly sealed in Nunc CryoFlex Tube Wrap (Cat. No. 343958). Improper use may cause entrapment of liquefied nitrogen inside the vial and lead to pressure build-up, resulting in possible explosion or biohazard release. Use appropriate safety procedures as outlined in the Nalge Nunc International Cryopreservation Manual when handling and disposing of the vials.
