Real-World Testing: Putting Nalge Nunc Round-Bottom Centrifuge Tubes, Polycarbonate, NALGENE 3117-0150, Pack of 10 to the Test
First Use Experience
My first field test involved collecting soil samples during a three-day ecological survey in the high desert. I used the Nalge Nunc Round-Bottom Centrifuge Tubes, Polycarbonate, NALGENE 3117-0150, Pack of 10 to store samples gathered at different altitudes and soil compositions. The temperatures ranged from below freezing at night to over 90°F during the day.
The tubes performed admirably, showing no signs of cracking or deformation despite the extreme temperature swings. Their clarity allowed for easy visual inspection of the samples. I appreciated the robust construction, as I didn’t have to worry about breakage when packing them into my backpack.
Initially, I overlooked the fact that closures weren’t included, which required a last-minute scramble to source compatible polypropylene closures (specifically the 21010-852 series, as recommended). Once I had these, the tubes were easy to seal, preventing any leakage.
Extended Use & Reliability
After several months of using the Nalge Nunc Round-Bottom Centrifuge Tubes, Polycarbonate, NALGENE 3117-0150, Pack of 10 in various field conditions, I can attest to their durability. They have been subjected to freezing temperatures in mountain environments, scorching heat in desert climates, and even accidental drops onto rocky surfaces.
Despite this rough treatment, none of the tubes have cracked or shown any signs of significant wear and tear. Cleaning is straightforward, as the polycarbonate material is resistant to most common solvents. Regular washing with soap and water is sufficient to remove any residue.
Compared to the thin-walled polypropylene tubes I used previously, the Nalge Nunc tubes offer superior protection and reliability. They have become an indispensable part of my field kit.
