Let’s Dive into Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, NALGENE 362820-0117 Natural Closures
The Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, NALGENE 362820-0117 Natural Closures, manufactured by Nalge Nunc, are designed for secure and reliable sealing of micro packaging vials, particularly in laboratory and research settings. These closures boast high-purity, low metal-content polypropylene copolymer (PPCO) construction, making them suitable for sensitive applications like PCR reagent storage.
My work in environmental sample collection and processing frequently involves storing small volumes of liquids, often needing to be cryogenically frozen or transported across rough terrain. Standard vials and caps can be unreliable, leading to leakage and sample contamination, so I needed a closure system specifically designed for secure micro-volume storage and transportation.
Upon receiving the closures, I was immediately impressed by their uniform appearance and the quality feel of the PPCO material. They felt noticeably more robust than standard polyethylene caps. These closures are seemingly designed for repeated use.
I had been using generic polypropylene caps for years, and have been frustrated by their inconsistent seal. I also considered closures from Corning and Kimble Chase, but the Nalge Nunc closures specifically mentioned low metal content and suitability for PCR reagents, a crucial factor for my research.
My initial impression was one of cautious optimism. They looked and felt the part, but the real test would be in their ability to maintain a leak-proof seal under various environmental conditions.
Real-World Testing: Putting Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, NALGENE 362820-0117 Natural Closures to the Test
First Use Experience
I tested the closures in the field during a week-long water sampling expedition in the Alaskan backcountry. Vials were filled with collected water samples and subjected to freezing temperatures, rough handling during transport by backpack, and exposure to varying humidity levels. I wanted to test their integrity in some difficult conditions.
The closures performed exceptionally well. Not a single vial leaked, even after repeated freeze-thaw cycles and jostling inside my pack. The ease of screwing and unscrewing the caps, even with gloved hands, was a notable improvement over my previous closures.
Initially, there was a slight concern about the caps becoming brittle in sub-freezing temperatures, but this proved unfounded. The PPCO material retained its flexibility and resilience throughout the testing period.
Extended Use & Reliability
After several months of consistent use in the lab and field, the Nalge Nunc closures have proven to be remarkably durable. There have been no signs of cracking or degradation, even with repeated autoclaving and exposure to various chemical solutions. This is crucial for maintaining sample integrity over time.
The closures are extremely easy to clean, and their smooth surface prevents contaminants from adhering. A quick rinse with distilled water and a wipe-down with a lint-free cloth is all that’s needed to maintain them. They have also proven compatible with various cleaning solutions I use.
Compared to the generic caps I previously used, the Nalge Nunc closures are a game-changer. They offer superior leak-proof performance, increased durability, and peace of mind that my samples are protected.
