Breaking Down the Features of Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342820-0114 Natural Closures
Specifications
The Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342820-0114 Natural Closures are characterized by several key specifications that contribute to their efficacy. The material is identified as PPCO, which stands for polypropylene copolymer, a robust and chemically resistant plastic suitable for laboratory applications. A critical feature is their Sterile status, achieved through gamma-sterilization (GST), ensuring they are free from biological contaminants.
These closures are designed for use with NALGENE Micro Packaging Vials, implying a precise fit and compatibility. The NNI No. 342820-0114 is the specific product identifier, ensuring traceability and ease of reordering. The “Natural Closures” designation refers to their uncolored state, allowing for clear visibility into the vial contents. The Color Coder: Green is an interesting specification; while the closures themselves are natural, this likely refers to an accessory or packaging identifier associated with this particular batch or type of closure, potentially aiding in inventory management or workflow segregation.
These specifications are crucial because they directly impact the reliability and safety of the sealed samples. The PPCO material offers good chemical resistance, preventing interaction between the closure and the stored substances. The gamma-sterilized (GST) nature is paramount for applications where sterility is non-negotiable, such as in cell culture or microbiological work, preventing the introduction of exogenous DNA or viral particles. The precise fit ensures a snug seal, minimizing the risk of evaporation or contamination.
Performance & Functionality
In terms of performance and functionality, the Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342820-0114 Natural Closures excel in providing a secure and consistent seal.
