A Wide Mouth Square Bottle is a laboratory container designed with a square-shaped body and a wide opening (mouth) for easy access and handling. This bottle style is commonly used for storage, mixing, and dispensing of liquids, powders, or solid samples in scientific, pharmaceutical, and industrial labs. The wide mouth facilitates easy filling, pouring, and cleaning, making it ideal for substances that require frequent access or transfer with minimal spillage. The square body offers space-saving advantages by allowing bottles to be closely packed on shelves or in storage racks without wasted space between round containers. These bottles are manufactured from various materials, including borosilicate glass (for chemical resistance and thermal stability), high-density polyethylene (HDPE) or polypropylene (PP) (for chemical resistance and durability), and sometimes polycarbonate for clarity and toughness. The bottle usually features threaded necks compatible with screw caps or closures to ensure secure sealing, preventing contamination or evaporation.
