Breaking Down the Features of Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342825-0110 Amber Closures
Specifications
The Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342825-0110 Amber Closures are crafted from high-purity, low metal-content polypropylene copolymer resin. This specific material choice is crucial for applications involving PCR reagents, as it minimizes potential inhibition of sensitive reactions. The closures are designed to be leakproof and feature a threaded screw mechanism for secure fastening.
They are manufactured to be noncytotoxic and nonpyrogenic, essential attributes for any product intended for biological or medical applications. The amber color is a key specification, providing protection against UV and visible light, which can degrade certain chemical and biological compounds. These closures are specifically sized to fit 11mm vials, ensuring a precise and tight fit with compatible NALGENE Micro Packaging Vials (such as the 16211-034 series).
Furthermore, these closures proudly meet stringent regulatory standards, including FDA CFR21 177.1520 and USP Class VI criteria. The NNI No. 342825-0110 uniquely identifies this specific product, and the absence of a dedicated color coder (indicated by ‘—’) highlights their straightforward, functional design.
Performance & Functionality
The primary function of these closures is to provide an impenetrable barrier for NALGENE Micro Packaging Vials, and they excel at this task. Their leakproof design is not an exaggeration; during my testing, even aggressive agitation did not result in any spillage. This absolute security is paramount for preventing sample loss and cross-contamination, especially in critical research or diagnostic settings.
A significant strength is their sterility. The fact that they arrive sterile, ready for immediate use without the need for additional decontamination steps, is a major advantage for busy laboratories. The PPCO material also performs admirably, showing no signs of leaching or interference with various sensitive reagents, including those used in PCR.
The amber coloration is a subtle yet vital feature. It effectively shields light-sensitive contents from degradation, a problem I’ve encountered with natural-colored caps in the past. The functionality is further enhanced by the noncytotoxic and nonpyrogenic properties, which are critical for maintaining the integrity of biological samples.
While these closures perform exceptionally well, it’s important to note their intended use. They are designed for specific vial sizes and applications. Attempting to use them on incompatible vials would likely compromise their sealing ability, which is not a flaw of the product itself but rather an issue of incorrect application.
