Large size reagent bottles are essential laboratory and industrial containers designed for storing and handling large volumes of chemicals, solvents, and reagents. These bottles are typically made from durable materials like polyethylene (PE), polypropylene (PP), or glass, ensuring chemical resistance and long-term storage stability. Common features include wide mouths for easy filling, secure screw caps or dispensing closures, and graduations for volume measurement. They are widely used in research labs, pharmaceutical production, and industrial processes. Products in this category may include carboys, amber bottles for light-sensitive liquids, and bottles with specialized coatings for corrosive substances. Sizes typically range from 1 liter to 20 liters or more.
