Real-World Testing: Putting Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342820-0112 Natural Closures to the Test
First Use Experience
My initial test involved using the Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342820-0112 Natural Closures to seal vials containing water samples collected during a backcountry water quality assessment. These samples needed to be transported securely for subsequent laboratory analysis. The vials were packed into a rigid case inside my pack and carried through varied terrain.
The closures performed flawlessly, even in fluctuating temperatures and after being jostled during the hike. No leaks were observed, and the seals remained tight and secure. The ease of screwing them on and off, even with gloved hands, was an unexpected bonus.
I didn’t need any time to acclimate to using them; the threading was smooth and intuitive. The only initial “issue” was more of an observation: the closures’ natural color made it slightly harder to visually confirm a complete seal in low-light conditions compared to colored closures.
Extended Use & Reliability
After several months of consistent use in diverse field operations, the Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342820-0112 Natural Closures have proven their worth. They consistently provide a reliable, leak-proof seal, maintaining the integrity of various samples, including water, soil extracts, and simulated biological materials. There are still no leaks.
The closures have exhibited minimal signs of wear and tear, even after repeated use and exposure to sunlight and temperature fluctuations. The PPCO material seems highly resistant to cracking or deformation. Their durability has certainly impressed me.
Maintenance is straightforward; a simple wipe down with isopropyl alcohol is sufficient to keep them clean and sterile. I’ve found them to be far easier to clean than closures with complex geometries or textured surfaces. Compared to previous closures I’ve used, these Nalge Nunc closures offer superior reliability and ease of maintenance, making them a worthwhile investment.
