Real-World Testing: Putting Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342825-0115 Amber Closures to the Test
First Use Experience
My first field test involved a week-long ecological survey in the high desert of Nevada, collecting soil samples for microbial analysis. The closures were used with the recommended NALGENE Micro Packaging Vials in fluctuating temperatures and dusty conditions. The threaded screw design made securing the vials straightforward, even with gloved hands.
The amber tint proved beneficial, shielding the samples from intense sunlight, which could degrade certain microbial components. After the first day, all vials remained leak-proof, and the closures showed no signs of deformation despite exposure to UV radiation and temperature swings. This performance was exactly what I expected.
Extended Use & Reliability
After several months of frequent use across diverse environments, from humid coastal regions to arid mountain ranges, the Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342825-0115 Amber Closures have consistently performed well. I’ve noticed no signs of significant wear and tear; the threads remain sharp, and the PPCO material hasn’t cracked or become brittle. Cleaning is simple; a quick rinse with distilled water and a wipe down with a lint-free cloth is all that’s needed to maintain their integrity.
Comparing these to previous closures I’ve used, particularly standard polypropylene caps, the Nalge Nunc closures offer a superior level of reliability and confidence. The sterile certification and amber protection provide added value, making them a worthwhile investment despite the higher cost, and in this environment, they drastically outperformed expectations.
