Real-World Testing: Putting Nalge Nunc Labtop Coolers, 20 C, NALGENE 5115-0012 to the Test
First Use Experience
My initial test occurred during a week-long ecological survey in the Mojave Desert. I pre-chilled the Nalge Nunc Labtop Coolers, 20 C, NALGENE 5115-0012 in a -80°C freezer before loading it with several vials of RNA samples collected from desert flora. Despite ambient temperatures soaring above 110°F (43°C) during the day, the cooler maintained its internal temperature remarkably well.
The cooler’s performance even exceeded expectations in the arid desert conditions. The samples remained frozen solid throughout the day, giving me confidence in its ability to withstand extreme temperatures. Using the cooler was incredibly simple; the pre-chilling was the only preparation required.
The only slight surprise was the rate at which the internal temperature rose once the cooler was opened to insert or remove samples. This required quick and efficient handling to minimize temperature fluctuations.
Extended Use & Reliability
After several months of use across various field projects, the Nalge Nunc Labtop Coolers, 20 C, NALGENE 5115-0012 has proven to be exceptionally reliable. The polycarbonate shell has withstood significant bumps and jostles without any signs of cracking or damage. Cleaning is straightforward; a simple wipe-down with a disinfectant solution is all that’s needed.
After repeated use, the cooler shows no signs of diminished performance. The temperature remains consistent, and the lid still creates a tight seal. It outperforms any previous attempts I’ve made at field sample preservation using makeshift methods.
