Real-World Testing: Putting Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342820-0116 Natural Closures to the Test
First Use Experience
My initial test involved a multi-day backcountry excursion focused on collecting water samples from various sources for later microbial analysis. I used the Nalge Nunc Closures on vials containing samples from a high-altitude stream, a stagnant pond, and a potentially contaminated spring. These vials were then subjected to the rigors of being jostled in my pack during the hike.
The Nalge Nunc Closures performed admirably in all conditions. Despite exposure to variable temperatures, humidity, and physical stress, there were no signs of leakage or compromised seals. The closures proved easy to apply and remove, even with gloved hands in cold weather.
After the first outing, I was particularly impressed with the closure’s resistance to temperature fluctuations. The varying temperature from daytime sun to nighttime cold did not affect the seal or the integrity of the closure. No signs of any issues were apparent.
Extended Use & Reliability
After several months of consistent use across multiple expeditions, the Nalge Nunc Closures have proven to be remarkably reliable. There is no leakage even after months of storage of various liquids. Minimal wear and tear is also evident.
The PPCO material demonstrates excellent resistance to degradation and maintains its structural integrity. Routine cleaning with mild detergents and sterilization with isopropyl alcohol have had no adverse effects on the closures. The material does not seem to be affected by even more caustic cleaning solutions.
Compared to previous experiences with less reliable closures, the Nalge Nunc Closures have dramatically reduced the risk of sample contamination and loss. They have consistently outperformed makeshift solutions and lower-quality alternatives. This has led to more confidence in the accuracy of test results.
