Real-World Testing: Putting Nalge Nunc Boston Round Bottles, Teflon Resin FEP, Narrow Mouth, NALGENE 1600-0016 to the Test

First Use Experience

My initial foray with the Nalge Nunc Boston Round Bottles, Teflon Resin FEP, Narrow Mouth, NALGENE 1600-0016 involved a multi-day backcountry excursion in a region known for its volatile atmospheric conditions and extreme temperature fluctuations. I used one bottle to store a concentrated cleaning solvent essential for equipment maintenance in the field, and another for a specialized analytical reagent. The bottles were subjected to freezing nighttime temperatures and direct, scorching midday sun, often within the confines of a packed rucksack.

The performance under these varied conditions was nothing short of remarkable. Even when filled with a solvent that would typically cause severe etching in lesser plastics, the FEP material showed no signs of degradation. The narrow mouth design, paired with the leakproof Tefzel* ETFE screw cap, proved invaluable in preventing any spillage, even during strenuous hiking and scrambling.

Ease of use was straightforward, though the narrow mouth required a slightly more deliberate pouring action than wider-mouthed bottles. This, however, is a minor trade-off for the enhanced containment and reduced evaporation it provides. The autoclavable nature was also a significant plus, allowing for thorough sterilization between different uses or after handling particularly potent substances.

One minor surprise was the slight rigidity of the Tefzel* ETFE screw cap at extremely low temperatures. While it remained perfectly functional and sealed, it required a bit more force to tighten fully when the ambient temperature dipped below zero. This is a characteristic of many robust polymers in extreme cold, and a small price to pay for its overall resilience.
