Culture medium bottles are essential laboratory consumables used for storing and cultivating microbial or cell cultures. These bottles are typically made of high-quality borosilicate glass or durable plastic materials like polycarbonate (PC) or polystyrene (PS), offering transparency, chemical resistance, and autoclavability. Common features include sterile packaging, graduated markings, and vented caps for gas exchange. Products in this category may include Erlenmeyer-style culture bottles, baffled bottles for improved aeration, and specialized designs like spinner flasks for suspension cultures. Sizes range from small 50ml bottles to large 2000ml vessels, with options for screw caps, septum seals, or filter membranes. These bottles are critical for microbiology research, biopharmaceutical production, and tissue culture applications.
