Breaking Down the Features of Nalge Nunc Fluorinated Solvent Wash Bottles, NALGENE 2421-0500, Pack of 2
Specifications
The Nalge Nunc Fluorinated Solvent Wash Bottles, NALGENE 2421-0500, Pack of 2 are built with specific materials to handle challenging fluids. The bottle itself is constructed from FLPE (Fluorinated High-Density Polyethylene), a material chosen for its exceptional chemical resistance. The closure, stem, and draw tube are made from FLPP (Fluorinated Polypropylene), further enhancing the chemical inertness of the entire dispensing system.
Each bottle boasts a 500 mL (16 oz) capacity, making them a practical size for field use or laboratory benchtop applications where large volumes aren’t necessary but consistent dispensing is. The closure size is 53 mm (2 1/16 inches), which is substantial enough for a secure seal and easy filling. The NNI Number for this specific product is 2421-0500.
These specifications are critical because they directly address the core challenge of dispensing solvents. Standard plastics can degrade, leach chemicals into the solvent, or become permeable, leading to evaporation and loss of product. The fluorinated materials used here, however, are known for their excellent resistance to a wide range of solvents, including hydrocarbons, ketones, and chlorinated solvents. This means minimal absorption and permeation, ensuring the purity of the dispensed fluid and reducing waste. The unit being a pack of 2 also provides immediate redundancy or allows for the storage of two different solvents simultaneously.
Performance & Functionality
In terms of performance, the Nalge Nunc Fluorinated Solvent Wash Bottles, NALGENE 2421-0500, Pack of 2 excel.
