My first impression was one of quiet confidence; these were caps designed to do their job without fuss.
Real-World Testing: Putting Nalge Nunc Polypropylene Screw Caps, NALGENE 362150-0130, Case of 2000 to the Test
First Use Experience
My initial foray with the Nalge Nunc Polypropylene Screw Caps, NALGENE 362150-0130, Case of 2000 involved setting up a series of environmental monitoring stations in a coastal salt marsh. This environment is notoriously harsh, with high humidity, pervasive salt spray, and significant temperature fluctuations.

Attaching these caps to both narrow-mouth and wide-mouth Nalgene bottles was remarkably straightforward. The 13-415 Cap Size threaded smoothly, and I experienced no cross-threading issues whatsoever. This is a critical factor when working under pressure, perhaps with cold- or gloved hands.
Even when subjected to damp conditions and the gritty texture of dried salt, the caps maintained their grip and sealing integrity. The linerless design, a key feature, meant I didn’t have to worry about a liner detaching or degrading over time, a common failure point with lesser caps.
There were no immediate issues or surprises after this initial deployment, only a reinforcement of what I’d come to expect from Nalge Nunc: dependable performance.
Extended Use & Reliability
Over the subsequent months, these caps became an integral part of my workflow. They were used to seal everything from water samples for microbiological analysis to soil samples for chemical composition testing. The true test of their mettle came when I had to autoclave a batch of media.
The instructions were clear: “Before autoclaving, set cap on top of container without engaging threads.” Following this protocol, the caps performed admirably through multiple sterilization cycles. They showed no signs of warping or degradation, a testament to the quality of the polypropylene material used.
In terms of durability, the robust construction has held up exceptionally well. Even after repeated opening and closing, the threads remain sharp and secure, ensuring a tight seal every time.
