Real-World Testing: Putting Nalge Nunc NALGENE Screw Caps, High-Density Polyethylene, Sterile 342151-0384, Case of 240 to the Test
First Use Experience
My initial testing ground for the Nalge Nunc NALGENE Screw Caps, High-Density Polyethylene, Sterile 342151-0384, Case of 240 was a week-long backpacking trip in the Sierra Nevada mountains. I used them on a variety of Nalgene bottles filled with water, iodine solution for water purification, and a concentrated electrolyte mix. The caps were subjected to varying conditions, including high altitudes, fluctuating temperatures, and the jostling of my backpack.
The caps performed admirably in all tested conditions. Even after repeated opening and closing, the seals remained tight, preventing any leaks. The ease of use was also noteworthy; no special tools or techniques were needed to achieve a secure seal.
The only surprise was how easily the smooth plastic surface could become slippery when wet. While not a major issue, it required a slightly firmer grip when opening or closing the bottles with wet hands.
