Narrow Mouth Amber Reagent Bottles (ASTM Standard) are laboratory-grade containers made from amber borosilicate glass, specifically designed to store and dispense light-sensitive chemicals and reagents. These bottles conform to ASTM (American Society for Testing and Materials) standards—commonly ASTM E-438—ensuring consistency in size, thermal resistance, and chemical durability. The narrow mouth design reduces the risk of spillage, contamination, and evaporation, while the amber coloration filters out ultraviolet (UV) and short-wavelength visible light, providing optimum protection for photosensitive substances such as iodine solutions, silver compounds, and certain pharmaceuticals. Bottles are typically supplied with ground glass stoppers or polypropylene (PP) screw caps, depending on application needs. They are suitable for use in a variety of environments, including analytical labs, pharmaceutical R&D, and chemical manufacturing.
