Real-World Testing: Putting Nalge Nunc CryoTube Vials, Polypropylene, Internal Thread with Screw Cap, NUNC 379146 Starfoot Self-Standing Vials Round-Bottom, Pack of 300 to the Test

First Use Experience

My first experience with the Nalge Nunc CryoTube Vials was in the remote Mongolian Altai mountains, where we were collecting blood and tissue samples from snow leopards. The vials were utilized in extremely cold conditions, often below freezing, and at high altitudes, pushing their material properties to the limit. I was particularly interested in if they would become brittle and potentially fail in such environments.

Despite the harsh conditions, the Nalge Nunc CryoTube Vials performed flawlessly. The screw caps were easily manipulated, even with gloved hands, and the vials stood securely on the uneven ground thanks to the starfoot base. There were no issues with cracking or leakage, even after repeated handling in the frigid air.

Extended Use & Reliability

After several weeks of rigorous field use, involving constant exposure to varying temperatures and rough handling, the Nalge Nunc CryoTube Vials continued to prove their worth. We transported the vials in liquid nitrogen dry shippers by helicopter and jeep. We even strapped some directly to trekking packs in order to preserve these precious samples.

The vials showed no signs of degradation or wear and tear, even after prolonged exposure to extreme cold and UV radiation. They remained airtight and leak-proof, ensuring the integrity of the samples. They are also quite easy to clean and can be sterilized with standard laboratory procedures. Compared to cheaper alternatives I’ve used in the past, the Nalge Nunc CryoTube Vials far exceeded expectations in terms of durability and reliability.
