Specifications

The Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342820-0118 Natural Closures are designed with specific features in mind for demanding lab applications.

• Material: The closures are made from high-purity polypropylene copolymer (PPCO), selected for its low metal content and resistance to many chemicals. PPCO also demonstrates excellent low-temperature performance, making it ideal for freezer storage.
• Sterility: Each closure is sterile, ensuring that it will not introduce any contaminants to the vial contents. This is critical for applications requiring absolute purity, such as PCR reagent storage.
• Size: These closures are designed for 11mm NALGENE micro packaging vials, providing a secure and leakproof fit. Their precise dimensions are essential to maintaining the integrity of the seal.
• Leakproof Design: The threaded screw closure ensures a tight, leakproof seal, even during temperature fluctuations or transportation. This prevents sample loss and cross-contamination.
• Color: The closures are available in a natural color, which helps with visual inspection and identification of the vials.
• Color Coder: The provided model (342820-0118) includes a purple color coder.

These specifications are crucial for maintaining sample integrity. The sterile, leakproof design ensures that samples remain pure and uncontaminated, while the PPCO material guarantees compatibility with a wide range of chemicals and temperatures. The precise fit and reliable seal offered by the Nalge Nunc Closures for NALGENE Micro Packaging Vials, PPCO, Sterile, NALGENE 342820-0118 Natural Closures translates directly to more reliable experimental results and reduced costs associated with sample loss or contamination.
